The Occupy Wall Street movement is understandable.
In the US, 16.5% of the population are without work and 6.2 million have been looking for a job for six months.
More than 40 million people are on food stamps.
In addition, America has a great wealth inequality; the 400 most wealthy Americans have a greater combined wealth than the bottom 150 million Americans - the top 1% being richer than the bottom 90%.
In addition, between 2002 and 2007, 65% of the economic gains went to the richest 1%.
In 2010, 25% of the top 100 CEOs took home more than their companies paid in corporate income tax.
However such wealth and income inequality may inhibit on growth.
A recent study of 65 industrial countries indicates that those nations with a greater inequality of income experience a slower growth than those with countries where incomes are more equal.
