As of now, not only have we failed to fix these three problems, but we’ve made them all worse. The big banks are bigger than ever, after having swallowed up their failed competitors. (Merrill Lynch, for example, is now a subsidiary of Bank of America; don’t believe for a minute that BofA’s senior management or board of directors has a remotely adequate understanding of the risks that Merrill is taking.)

Interconnectedness, too, has increased. With the bailout came a deluge of liquidity, courtesy of Ben Bernanke: the Fed bailout was tantamount to dropping billions of $100 bills from helicopters over Lower Manhattan. That money got spent on financial assets—that was the whole point—and as a result, financial assets started moving in conjunction with one another. If my shares are rising, your shares are almost certainly rising too. And your commodities, and your municipal bonds, and your Old Master paintings. Because of this increase in financial correlation, if and when another crisis hits, it will be uncontrollable: it’s certain to strike absolutely everything, all at once. And though some people think Congress can simply regulate the problems away, there’s no way to legislate solutions to problems that are endemic to our financial system.
