Recall that Citigroup was brazenly created in 1998 in violation of the Glass-Steagall restrictions. Those were repealed within months with major help from Robert Rubin, who went on months later to make $15 million a year at Citigroup. The repeal was like waving the green flag at a Nascar race—part of a culture of empowerment that encouraged Wall Street to get bigger and riskier and to eventually trash the rest of the economy.

But don’t listen to me or Sorkin: Ask John Reed, Citi’s former CEO, and Dick Parsons, its former chairman.
