During his interview with the New York Daily News, Bernie Sanders was asked to specify the fraud committed by Wall Street banks. He replied:

What kind of fraudulent activity? Fraudulent activity that brought this country into the worst economic decline in its history by selling packages of fraudulent, fraudulent, worthless subprime mortgages. How's that for a start? Selling products to people who you knew could not repay them. Lying to people without allowing them to know that in a year, their interest rates would be off the charts. They would not repay that. Bundling these things. Putting them into packages with good mortgages. That's fraudulent activity.

Does Sanders really forget that it was progressives like him who demanded that banks lower lending standards so that low-income people with no, weak, or bad credit histories could get mortgages with low teaser interest rates that would later balloon? Is he ignorant of the fact that these banks had every reason to believe the government would bail them out if they failed? Does he not recall Fannie Mae and Freddie Mac, the government-sponsored enterprises championed by Barney Frank and other progressives, that were right in the middle of this action, knowing they'd be saved if they failed? Has Sanders no memory of mortgage lenders like Countrywide, which were celebrated by progressives for aggressively pushing mortgages on people who could not afford them? Is he unaware that the Department of Housing and Urban Development (HUD), under Bill Clinton (and Secretary Andrew Cuomo) as well as George W. Bush, enabled people with poor credit and low incomes to "buy" houses with little or no down payment? And finally, is he oblivious to the fact that it was all these government-pushed shaky mortgages that were bundled into the exotic investment instruments Sanders now decries?

I'm pretty sure Sanders is aware of all this. But it doesn't fit his narrative that the Great Recession was entirely the result of private-sector greed, so he can't acknowledge it. Wall Street is properly viewed with suspicion, but what makes that reasonable is that it has long been in cahoots with the national government, notably with federal deposit insurance, which rewards irresponsibility by relieving depositors of the need to judge banks' sobriety or lack thereof.

In other words, Sen. Sanders, Wall Street couldn't have done it alone. It needed people like you.
