So you support paying labourers peanuts? He's asking for $10 because that's all you'll pay him. I Qatar, that $10 he charges won't even feed him and put a roof over his head. But hey, you got cheap labour. Kinda sounds the same as what companies are doing here. So I guess you support discrimination Lamea as long as it benefits you.
A western mechanic would live an average middle class life at the rates he charges. If a mechanic in your country lives an average middle class life charging $10, there is no dispartity. They both get the required amount to maintain the same relative standard of living. This equation is also used here to determine wages according to home country.
