But they don't know enough to make well-informed decisions, do they - that's what recessions are all about. People with false ideas about the economic prospects make overly cautious choices, which make the economic prospects even worse - a self-fulfilling prophecy.

You've got the world's most expensive health care, and while it's adequate for the people with full health insurance, it's rotten for everybody else, which exposes even the fully insured to unnecessary health risks. Getting it into a state where it can match French or German health care is going to take a while, and the Republicans haven't got a clue how to get there, no any real idea that's it's necessary or desirable.
