...an even more interesting response. So you are, in essence, saying costs in other countries are lower, because the costs are lower?
I'm not sure what a "lost income" is? Are you suggesting someone took over a physicians practice and made them work for peanuts? What physicians make in other countries they understood when they became physicians. It ain't peanuts and most are at the upper end of the socio-economic ladder, as they are here.

Before you cry too many tears for the poor abused physicians realize that in most countries, higher education is substantially, if not fully, paid for. Doctors elsewhere do not start day one with a $170,000 in debt, as they do here, so salary demands aren't as high. Moreover thecost of affluence in most other countries is far, far lower than it is in the US. Because of wealth disparity, the price of admission to the good life is much higher here than in other countries. People can live better on less money then they do here.

So, as we agree, medical costs are lower in other countries, because medical costs are lower in other countries...
Of course, then there is this little matter of insurance companies, the unnecessary middle man of medical administration. Countries with national healthcare don't have the cost of this unnecessary middle man, not do they have to finance the $5.0 million salaries and bonuses of unnecessary CEO's ($66M was the all-in compensation of the CEO of United Healthcare in 2014)

Aren't as many hands in the medical till in other countries... another reason costs are lower.
