Oh yes, even if (that's a big IF) med school in those countries costs $1000 a year, you're talking more than a year's salary for most people. Kinda like it costing $30,000 a year in this country.

Then, you have to remember, that all the infrastructure that the other country spent to train that doctor gave benefit to the US, not the original country. The US is getting a bargain in the deal.
