But what about that half of or so of the American labor force that isn't brain surgeons ? That half or so that does exactly the same work that Ram or Chan or Felix do but at a tenth of the cost. They have NO comparative advantage.
The brain surgeon is in cheap labor paradise because the AMA controls entry into the medical marketplace and will not allow foreign doctors to drive down the fees of American doctors. Everyone else is not.
Comparitive advantage should be renamed relative advantage. A shoesaleman (think al bundy) can sell shoes and do lawn mowing cheaper than jose. But it will still be in his advantage to sell shoes and hire jose. In other words, do what you do best and outsource(domestically or internationally) the rest. The law of comparitive advantage is really a mathematical description of common sense.
What medical buildings do YOU go to? ;o)
