That $10 billion is evidence of their magic trick. For we the taxpayer gave Goldman Sachs the following:
10 Billion in TARP
11 Billion from the Fed
30 Billion from the FDIC
13 Billion from AIG
For a grand total of almost $70 Billion (Goldman along with every other bank and AIG would have been defunct without this money).
Goldman at the apex of the crisis is delivered this money -- which they then use to borrow against at $20 or $30 for every $1. Which at 30x equals $2.1 trillion in available capital.
