There are many elements to the current economic system that threaten to tear it apart; so many that we will have to approach the design piecemeal, with the hope of eventually integrating all the pieces into one flowchart.
One aspect is the benefits trap. Undermining our domestic workforce by putting them in competition with far lower-paid people around the world has meant wages have stagnated, while in order to keep up with inflating living costs those out of work cost more to keep and those in work often need some form of in-work financial supplement.
The gap then narrows to the point where the unemployed cannot afford to work and the lower paid wonder why they bother to work. Responding to Sunday's post here, "Jack Ketch" says:
" A life on welfare today probably gives you a better standard of living than a working man had 40-50 years ago"
Bollocks does it! If I wanted to live in that kind of poverty, the soul destroying grinding poverty of Granddad's era, I'd go get a job....and yes I am genuinely on benefits. We pull in something like £1k a month cash in hand and the rent is paid. Going to work is a luxury many can't afford, that's the stone cold truth.
As the old song goes:
I was outside a lunatic asylum one day, busy picking up stones
When along came a lunatic and said to me, "Good morning Mr. Jones,
Oh, how much a week do you get for doing that?" "Thirty bob!" I cried.
"What, thirty bob a week, with a wife and kids to keep?
Come inside, you silly bugger, come inside."
"Come inside, you silly bugger, come inside, you ought to have a bit more sense.
Working for your living, take my tip, act a little screwy and become a lunatic.
Oh you get your meals most regular and a brand new suit besides.
What's thirty bob a week with a wife and kids to keep?
Come inside you silly bugger come inside."
