If you don't believe in (recognize) white privilege why the fuck are you on a Democratic Forum?

75. For two good introductions, I recommend...

1. The Case For Reparations, an Atlantic piece by Ta-Nehisi Coates, and
2. Fear Itself, the New Deal and the Origins of Our Time, a book by Ira Katznelson

In addition, Coates lists several deeper treatments of the question in his article, a particularly popular (and good) one is The Warmth of Other Suns, a history of the Great Migration by Isabell Wilkerson.

Nonwhites had almost no wealth.

A common misconception. Nonwhites generated a ton of wealth, and it was repeatedly either taken from them, or in some cases simply destroyed. The means of appropriation were varied, and ranged from entirely illegal, through vaguely extralegal, to outright codified by law. Actions like the Tulsa riots, the Wilmington coup d'etat, and the Rosewood massacre (to pick three off the top of my head; there were hundreds) stole what black wealth could be stolen, and destroyed the rest.

And how the New Deal is responsible for this theft.

It's hard to do justice to this question at less length than Coates did, and Katznelson's very thorough treatment is even better for it. To summarize: the New Deal deliberately excluded minorities from the safety net it created by several means: jobs that were often held by nonwhites were left out of social security and medicare, and assigned a lower minimum wage; nonwhites were (by FHA and USDA policy) given home and farm loans that were designed for them to default so their property could be confiscated; later, nonwhite veterans were denied access to the GI Bill. Furthermore, during this period a "second plantation economy" developed in the south (and west, for that matter) based on mostly nonwhite convict labor from state and Federal prisons (with unemployment itself being a jailable crime) -- this isnt just a throw-away point: the numbers involved are staggering.

Meanwhile, at the other end of the Great Migration in northern cities, organized labor systematically shut nonwhite workers out of protections and membership. The labor/capital/government triumverate that the New Deal was based on was, for a variety of political reasons, entirely oriented towards taking wealth from nonwhites to the advantage of whites.

I would like to know how much wealth was stolen and where it came from

We don't know for certain because Congress refuses to allow a vote on John Conyer's repeated initiatives to study the question. Preliminarily, the largest amount of theft seems to have been of homes and farms through a variety of means, but then again the educational and economic policies that prevented accumulation of capital were perhaps even bigger. We could have a better answer if Congress would study the issue...
