Taiwanese doctors don't get paid in money.
They get paid "credits" which have to be exchanged for money based on a parallel financial system.
Foreigners here sometimes complain that there's a focus on seeing more patients faster, so there might be a misdiagnosis or a less thorough examination.
The fact remains though - it's cheaper to fly here to have a wisdom tooth removed (without insurance) than the same operation would cost in Switzerland or the US. There isn't much resentment of medical tourism either - so, you're all welcome to visit!
