"Average wealth" of any specific sector of the population serves well to skew the discussion about overall economic conditions in the US. While black people are disproportionately poor, the great majority of US poor are white, and this has always been true. Black people don't know that white poverty exists, and white people pretend it doesn't. IF US poverty is mentioned at all, we call poor black people "disadvantaged," and poor white people "white trash," and regard them accordingly.
Then there's the bigger story. From FDR to Reagan, the US had implemented a range of policies and programs, with a focus on poverty reduction, that actually took the country to its height of wealth and productivity (far from utopia, but much better). Then we changed our minds. We reversed the policies, ended the programs, and created one hell of a poverty crisis that this generation of liberals choose to ignore.
Here's reality: Not everyone can work (health, etc.) and there aren't jobs for all. The US shipped out a huge number of jobs since the 1980s (many are still leaving), ended actual welfare in the 1990s, and pretends there are no consequences.The last I heard, there are 7 jobs for every 10 jobless people who still have the means to pursue one (home address, phone, etc.), and this country has NO mercy on those who are left out.
Bottom line: Our corporate state couldn't care less about the color of those it can exploit and discard.
