This sounds like a made up number. What is your source?
> The 2008 Mortgage crisis robbed the working classes
How? I.e. what did working class people own that was subsequently taken away by some other entity?
> Wall Street over leveragged had huge wealth handed to them in money printing that was giving directly to their balance sheets.
A common misconception. The government did recapitalize various Wall St. entities on favorable terms, and did, via quantitative easing, give owners of some securities more than they might have gotten in the market without intervention. But there were certainly not any "no strings attached" givings of cash to the big financial entities.
The other stuff about how working Americans were the ones most hurt by the financial crisis also sounds incorrect to me. If I had to categorize winners and losers, owners of mortgage debt and homeowners would be the biggest losers of the crisis. Working Americans suffered knock on effects, or direct effects to the extent they were in the other categories, but they were not the primary victims.
