WHO WERE THE BANKERS WHO WORKED FOR THE BIG WALL STREET BANKS AND SMALL HEDGE FUNDS DURING THE 2007/8 FINANCIAL CRISIS?

The film The Big Short examines how the financial crisis of 2007/8 occured from the view of two small hedge funds' interaction with the big banks of Wall Street. Every major character is a white American male with one or two minor characters being of colour or women.

Is that historically accurate?

Who exactly were these bankers and hedgers?

Who worked for the big Wall Street banks, or even a small hedge fund, and not necessarily in the USA?

What was their profit? Loss?

Did they know exactly what was going on but kept their mouth shut to make that profit/loss?

What was their gender? Ethnicity? Religion? Politics?

It must be in the tens of thousands around the globe. That would make a good population for a statistical analysis of their psychology.

But who would admit to allowing and profiting from that crisis?
