Can you kindly also cite the studies which show that the level of social mobility in America is now one of the lowest in the industrial world?

Luck, particularly how much wealth you were born with, plays a large role in your likely social outcome, in ways which cast serious doubt on the success of the layout and rules of the economic system under which we attempt to flourish.

If you follow that logic, when you look at historical state-sanctioned inequality, from slavery to Jim Crow to de-facto de-segregation to the present, what we're witnessing isn't a continuation of Jim Crow. The lack of social mobility here (a raceless consideration) has condemned those who've started off many meters behind the 'Start' line of the race.

THAT is the interplay between race and class.

The fact that we can only articulate this in terms of race is the genius of how the dialogue continuously shifts away from wealth inequality (in America the top 1% own 40% of the wealth) and into discussions of white versus black. Now, the average white person and the average black person are pitted against one another, instead of BOTH screaming against this very fact.
