@ddljohn-- Yes. I too saw a similar article, from 2013. It said that the US is the most unequal developed country in the world.
Despite this, Americans want to limit social services and the government wants to reduce taxes for the wealthy. So instead of trying to fix the problem, we are making it worse. In most other developed countries 44-65% of wealth is owned by the richest 10%. In the US, it's 75-80%.
What's surprising is that this nation was formed to give opportunity to those who did not have them in other countries. But when it comes to wealth, very small percent of the American population benefits.
This is a serious issue that we all should be thinking about, especially policymakers who make decisions to worsen this issue rather than fix it.
