When the rich are too rich, something is wrong

Chart of wealth distribution in the United States (1920-2005)

Look at the great resemblance between current situation in US, in terms of wealth distribution, and 1920s situation. According to a study by Thomas Piketty of the Paris School of Economics and Emmanuel Saez of the University of California at Berkeley, after a prolonged period of economic prosperity, both in the late 20s as in the recent last years, 20% of national income has been concentrated in 1% of the richest people. In contrast 90% of the U.S. population with the lowest income only account for 50% of total national income.

Perhaps, when the imbalance becomes excessive, more than 20% of total nacional income from only 1% rich population,  it’s a clear signal that something doesn’t works. Too many excesses have been committed.
