Open the borders

This idea for stimulating the US economy is so obvious yet so radical it is bound to be considered a joke.

The problem? The US has too many houses with too few people to buy them.
The solution? Grant a visa to any foreign national who can buy (and preferably live in) a house. If you are worried about such people becoming indigent wards of the stae, consider that if they have the savings to buy property and the verve to pick up and move here, then that's not so likely.

Thomas Friedman describes the plan here.
