The world's economic cancer - income inequality
Something we already know - but study shows just how devastating income disparity can be to ANY country in housing, sex discrimination, government representation, etc. And one of the prime reasons is that investment is rewarded, while labor is not (sounds rather like a Communist manifesto, doesn't it).
"The average annual income of the poorest 10 percent of people in the world has risen by less than $3 each year in almost a quarter of a century. Their daily income has risen by less than a single cent every year.
...apologists for the rich often cite the numbers of people worldwide living in extreme poverty was cut in half between 1990 and 2010 as proof that inequality is not a major problem. However, that misses the point, because had inequality within countries not grown during that period, an extra 200 million people would have escaped poverty.
Wealth trickles up, not down,says Oxfam, because the richest individuals use a system of global tax-avoidance schemes to avoid paying taxes to their governments. Once [wealth is] there, an ever more elaborate system of tax havens and an industry of wealth managers ensure that it stays there, far from the reach of ordinary citizens and their governments.
