I hope you can discern between the term 'salary' and 'income'. Although one's salary may be low, their income can be substantially higher, which is the case for doctors pretty much anywhere around the world.

In reality, they pick up money under the table from every treated patient, either due to their own charges or a patient's kind gesture. In any case, you can be assured they make a lot more than 200 USD per month.
