You're suggesting an unreal scenario, so the thought experiment isn't going to do much good, IMO. Each employee gets to make that call themselves, "do I want to be treated badly?"
Fresh graduates may not realise they are being treated badly, lacking a frame of reference. Immigrants may be on a visa where they have no choice but to put up with it or leave the country.
Locals who've been around a bit, who know their discipline, the proven (local) best of the best? They don't stay on teams led by bullies.
