Why isn't there a push to bring in the foreign doctors?
Bad example. There is a push, but we're looking at pure protectionism. Doctors have the AMA guild with enough money to make it near impossible for a doctor without an MD from a US institution to get a license to practice medicine in the US. You could be a naturalized citizen with a MD from a top British med school and have no hope of ever practicing medicine in theUS without going back to school.

Damn straight. Anyone who isn't ready for when TSHTF deserves the screwing they get!
