Robert Reich wants Obama to pop the credit bubble:
The bankers will tell Obama...that any new contraints on credit card lending will cause the banks to reduce the amount of credit card lending they do, which will hurt the economy. But it's a weak argument because it presupposes that any lending is good for the economy -- even lending to people who don't know what they're getting into and can't repay the loans. It's the same argument banks used two years ago, when precient observers warned that constraints had to be placed on mortgage lending practices. What may hurt the economy in the short term, we now know, may save it from even larger pitfalls to come.
