The CIA World Factbook gives global GDP per capita as $10,200 (in purchasing power parity terms). This puts the average standard of living somewhere between Kazakhstan and Mexico. On the same basis, per capita income is $43,800 in the USA and $31,800 in the UK .
Generally, the poorer the country, the higher the income inequality as measured by the Gini Index (except for Azerbaijan, according to this from the ESRC).
The Factbook estimates 30% combined unemployment and underemployment in many non-industrialized countries; developed countries typically 4%-12% unemployment.
There are enormous fortunes to be made (by some) arbitraging the economic differences between countries.
In the USA and the UK, we are relentlessly spending more than we are earning.
What are our governments' plans for us to remain rich? And given the correlation between income and equality, do our business, media and political elites have much incentive to make and seek support for such plans?
