At 20k USD / month, you are either incredibly good and/or lucky or you are not saying that you are working in Switzerland, in which case you forgot to say that your cost of living is higher than SV and you have no public health insurance. (but 20k/month is comfortable anyway, even in Switzerland)

There are plenty of contractors in India making $8-10k a month so there must be thousands in EU making $11k a month or more due to proximity and language advantage.

Check freelancing sites to get some idea. Plenty of guys getting long term work at $60-$80 an hour.

That's how much is needed to be paid for getting people to do unethical work. It is not directly comparable to working on a compiler used by many people.

What about the people working on open source compilers at those companies (e.g. ReasonML at Facebook).
