US college math: If at first you don't succeed... by Paddington
There is current news on the intent of the state legislature to take over the State Board of Education, and the articles on the subject include a discussion of the 2021 Ohio Remediation Report. That report states that the percentage of students going to higher education and requiring remediation in Mathematics and/or English is declining.
Most of that gain appears to have been achieved by changing definitions.
When I started teaching Mathematics at the University of Akron in 1978, approximately 80% of the incoming students had not mastered Algebra I enough to pass a placement test into a college-level Mathematics course.
That 80% figure was national, often quoted as 'only 15% of 12th grade students were ready for a college-level Math course' (The difference in percentages was due to those students who didn't go to higher education).
When I retired in 2017, that 80% figure had not changed, despite the addition of lots of technology, and rounds of 'innovation' from Colleges of Education.
So, universities and colleges around the country were under pressure to 'fix the problem', and responded by generating courses which were not actually college-level, simply eliminating the requirement for a Math course, or re-defining what a Math course was. Others, such as the University of California system, have tried to hide the problem by 'just in time' remediation, which works about as well as one would expect.
After a half century of teaching and thinking about this problem, I wish I could have an answer, as a genuine solution would likely make me rich. I can, however, safely say that wishing it away doesn't help.

Reopen the talent mines! by Paddington
As Heinlein pointed out, the natural state of Man appears to be poverty.
Two hundred years ago, a person living on my property was 10 miles from the nearest small town. If he didn’t plan ahead, he would starve or freeze in the winter. Thanks to advances in technology, all but the very poorest of us now have access to clean water, cheap and safe food, and terabytes of bad information and pornography.
These advances were the result of government investment in basic science, including semiconductors, computers, nuclear energy and the internet itself. The researchers who did most of this were middle class through and through. Most engineers and scientists still are, and gain their training through the public education system. The well-educated children of the rich become lawyers, bankers, and sometimes doctors.
The contest between the creative geeks and the leaders of our societies go back over a millennium.
During the Middle Ages, many of the skilled workers were represented by the guilds, including the Freemasons. The Catholic Church kept their power in by controlling the spread of science and technology, while keeping the nobility largely illiterate. This balance of power shifted in the labour shortage that resulted from the Black Plague.
As the population increased, thanks to the dissemination of technology, the balance of power gradually shifted back, until the Scientific Revolution required skilled workers in large numbers. This led to the drive for public education.
In our lifetimes, we have moved to a Global economy, giving access to huge reservoirs of cheap labour. Our business and political leaders, most of whom do not know how to do anything practical, simply assume that the vast riches around them are the result of their own brilliance, and so are quite happy to move all of our jobs to other countries. They also work to dismantle the education system, and cut money for research, since this saves them taxes. The current economic crises give them the perfect excuse.
The problem is that simply preserving what we have as a society requires mining our meager talents every bit as aggressively as we drill for oil.

EMAIL FROM AMERICA (11): Work avoidance and worker exploitation
While there is loud praise of the Protestant Work Ethic, an awful lot of the culture is devoted to 'get rich quick' schemes and various forms of confidence tricksters, whose scams generally feed off greed. And it seems that this has been the case for a very long time, from the gold rushes in California, South Dakota and Alaska to gambling on the stock market in the 'bucket shops' of the 1890's, and more speculation in the events leading up to the crashes of 1929 and 2008. Not to mention the lottery, the illegal 'numbers games', Florida swampland swindles, evangelists, multi-level marketing schemes, Ponzi schemes, telephone 'psychics' and so much more.
It is almost as if most people were trying to avoid 'good, honest work' and always have.
The Jamestown colony in Virginia was established in 1607 by a group of 'adventurers' (read junior sons of nobility who wouldn't inherit) to make money, yet they had no skills or tools, and eventually had to import Polish workmen to actually build things. Interestingly, this led to the first American strike, when the colonists decided to set up a democratic system, without giving those workers a vote.
The famous Plymouth colony, founded in 1620, consisted of very pious individuals, who came with no tools or skills other than firearms. They would have died, and almost did, had it not been for the local tribes making alliances with them, and a few sailors electing to stay, with their tools and practical skills.
And who did the bulk of the dirty work to build the country for the next 200 years? In the Northeast, it was indentured servants and other poor immigrants from Great Britain and Ireland. In the South, it was enslaved African-Americans and Native Americans. In the West, it was poor Mexicans and imported Chinese, who were then quite badly mistreated by the Chinese Exclusion Act of 1882.
The rapid industrialization of the late 1800's demanded a concentration of workers, who then started to think about unionization. This led to cries of 'socialism' and 'anarchy' from the wealthy, who used every power of the government to stop them.
In 1920, efforts to unionize coal mines in West Virginia led to the Stone Mountain Coal Company hiring the Baldwin-Felts agency to evict the families of striking miners from the company-owned housing. In the course of their actions, the agents claimed to have a warrant (which turned out to be fake) to arrest the Chief of Police Hatfield in Matewan, which in turn led to a gunfight known as the Matewan massacre. This inflamed the miners, who embarked on a campaign of sabotage and harassment.
In the midst of this, Chief Hatfield went to an adjacent county in 1921 to stand trial on a count of sabotage. As he walked up the courthouse steps, Hatfield and his friend were murdered by Baldwin-Felts agents.
This event made things even worse, and the violence increased. This culminated in the Battle of Blair Mountain, where a force comprised of volunteers and members of the West Virginia National Guard and State Police met thousands of angry miners, resulting in several hundred deaths. The former used leftover bombs and poison gas from World War I in the course of the battle.
Once federal troops arrived, the miners, many veterans, refused to fire on US troops, and returned home.
After the subsequent arrests and trials, union membership in the United Mine Workers dropped from 50,000 to 10,000 and stayed low until the depths of the Depression in 1935.
It was not until the mid-1950s that unions became respected and the hard physical jobs well-paid. And that only lasted for 20 years or so, after which the Reagan administration tried to copy the model of Margaret Thatcher and reduce their power.

EMAIL FROM AMERICA (10): Hedge fund managers run riot
- pharmaceutical companies (resulting in huge price increases in many drugs, including insulin)
- restaurant chains such as Wendy's hamburgers
- medical testing facilities
- hospital systems
- medical groups (whose doctors are then reimbursed less and pushed for more 'output')
- dental groups (many of which are 'encouraged' to do things such as unnecessary root canal work)
- trailer parks (where many of the poorest live. They cannot move their trailers, so can be easily subjected to higher rents and maintenance fees)
- homes, especially in the Sun Belt (many are bought sight-unseen the instant that they go on the market, often for tens of thousands more than the asking price, then becoming very expensive rentals)

EMAIL FROM AMERICA (9): US medical price-gouging - you really want this for the NHS?
- approximately 10% of the population too poor to afford insurance (and not granted it by their work), and too rich to be on Medicaid
- some insurers kept up to 54% of premiums, with huge incentives to refuse payment
- maximum lifetime benefits, amounting to 10-15 years of treatment for something like hemophilia
- refusal to cover 'pre-existing conditions', which could include anything from pregnancy to cancer risks

EMAIL FROM AMERICA (5): Pharma's slaves, by Paddington
Banting refused to have his name on a patent because he felt that it was unethical for a doctor to profit from saving lives. Best and Collip sold the patent to the University for $1, citing similar feelings.
Fast forward a few decades, and many hedge funds have invested heavily in pharmaceutical companies, including every manufacturer of insulin in the US. In order to make the most of their investments, they have bought political influence to make competition more difficult, and have increased prices to maximize their profit.
Bearing in mind that the standard explanations of development costs and safety checks really do not apply for a drug developed 100 years ago, in which the newest changes are over 20 years old, one can note that the price of a vial of insulin in the Humalog brand went from $21 in 1999 to $332 in 2019.
And those costs have not risen at the same rate elsewhere. In 2018, the Rand corporation listed the 10 countries where insulin was most expensive: The USA $98.70, Chile $21.48, Mexico $16.48, Japan $14.40, Switzerland $12.46, Canada $12.00, Germany $11.00, South Korea $10.30, Luxembourg $10.15 and Italy $10.03.
On Friday, the US House of Representatives voted on a bill to reduce the copay (what the consumer pays) of insulin to $35. This move to reduce prices is part of the GOP platform, yet only 12 Republicans voted for the bill, and 193 voted against it.
And insulin is just the tip of the iceberg.
Hedge fund manager Martin Shkreli bought the rights to Daraprim, a decades-old drug used to treat a fatal parasitic infection, and raised the price for a pill from $13.50 to $750. He went to prison shortly thereafter - not for this disgusting behaviour, but for defrauding some investors in his hedge fund.
Mylan purchased the rights to the EpiPen self-injector (to treat life-theatening allergic reactions) from $50 per unit to $300 over a few years, resulting in massive increases in profits and huge rewards for CEO Heather Bresch, who just happens to be the daughter of quasi-Democrat Senator Joe Manchin of West Virginia. The latter has been one of the two Democratic senators responsible for blocking much of the people-oriented legislation that the Biden administration has tried to pass.
Legal slavery ended in the US in 1865, but our lives and our health are still for sale.

EMAIL FROM AMERICA (3): misinterpreting the Founders and the Bible, by Paddington
Tracking the chaos...
This week brings the confirmation hearing of Judge Ketanji Brown Jackson to the Supreme Court. The GOP members in the Senate have vowed to vote against her, even though she is more qualified than most of the more junior members on the Court. At stake is her refusal to embrace 'originalism', a philosophy that we should do EXACTLY as the Founders said, not necessarily what they intended. In support of this onerous and odious idea, the conservatives repeatedly make up quotes by people such as Madison, and simply lie about the rest.
Via Heather Cox Richardson, US historian: A 2019 speech by then–attorney general William Barr at the University of Notre Dame offers an explanation.
In that speech, Barr presented a profound rewriting of the meaning of American democracy. He argued that by 'self-government' the Framers did not mean the ability of people to vote for representatives of their choice. Rather, he said, they meant individual morality: the ability to govern oneself. And, since people are inherently wicked, that self-government requires the authority of a religion: Christianity.

Education - why ? by Paddington
I went to school and got my undergraduate degree in England, in the 1960's and 1970's.
The educational system, then and there, was brutal in some ways. It was certainly unforgiving.
We took a test in the last year of primary school (5th grade), which determined which school in the county would accept you the next year, the top level generally being a grammar school, where the tradition was to focus on Latin, Greek and English literature. I actually went to something called a Mathematical school, established to train naval navigators in the 18th century.
Every year after that, most 'grades' were determined by exams taking mid-year and at the end of the year.
In the 5th year (sophomore), and sometimes a few the year before that, we took regional exams to determine competency in the chosen subjects. In my case, it was Astronomy, Chemistry, Mathematics, English, French, German, History, Further Mathematics and Physics. In Mathematics, we took the equivalent of most of the standard first semester college Calculus, plus the material college-level Precalculus. Tha languages exams included taking dictation, translation in both directions, writing essays, and having a conversation.
A poor performance meant that your school career was likely over. The successful (about 40%) then concentrated in 2-4 subjects, with a view to higher education. There was then another set of regional exams at age 18, which determined whether your university of choice would accept you.
At university, you were in the major which you had declared 18 months before, and there was basically no changing that. I took Mathematics, which meant that every class was Mathematics, Statics and Dynamics, Physics, Engineering, Computer Science, or Statistics.
We took exams immediately after Christmas break, merely to see how well we had adapted. At the end of that first year year, we took six 3-hour exams which simply determined whether we would be allowed back the next year, and which of two tiers of courses we would take.
For the second and third (and final) years, there were six 3-hour exams each year, with the level of the degree awarded based only on those exam results. There was no equivalent of GPA or academic transcript, problems which almost prevented me being accepted by a U.S. university for graduate study.
It was designed quite well to produce people who at least had a grasp of the basic content of their majors. It was also basically free of charge to the students and their families.
All of this has, of course, changed, with the U.K. adapting a version of the U.S. system, including having students pay their tuition, and a more liberal arts flavour. It is also much less selective, going from 5-10% in higher education in my generation to 50% now.
One result is many thousands of students living with their parents into their 30's with crippling debt.
It was a great culture shock to experience the very generous nature of a U.S. university, including many chances to retake courses, change majors, or even transfer between institutions. It is certainly a more generous one than I went through. I have many friends who succeeded in this system who likely would never have been given a chance under the one that I went through.
I have very mixed feelings after 40+ years as to whether it is better as a whole, given some of the many people that I know with massive college debt and no degree, and others with the illusion that they have been educated.
I have yet to determine what the actual goal of the U.S. system really is.
