Very interesting observation. It's also important to note that as doctors move from being employers to employees, they find themselves dealing with the same economic pressure from foreign labor that destroyed blue-collar jobs in so many industries here in the U.S.
The only difference is that workers in manufacturing jobs lost out when their jobs moved overseas. Workers in health care are losing out when the foreign labor moves right into their own offices and hospitals.
Also, nonsense. Foreign medical graduates are recruited to practices where American candidates can't be recruited or where demand outpaces supply for the American graduates.
