You seem to be arguing from abstract principles instead of considering the actual facts. What tristor has understood and you have not is: "People" are not all the same. I just explained why US workers are preferred or even required for a lot of ML tasks. Did you read that? As for exploitation, I'll limit myself to noting that certain people are always finding it whenever a rich person hires a poor person, despite the fact that nearly all jobs arise this way.
