Their choice? I think not. If you remove all other jobs and only offer one, do people who need work really have any choice other than to take it? Fresh young professionals right out of college have at minimum a 2 year wait before they find "any" work in China, usually longer. That being the case, some people have no choice. In some places the wait could be much much longer. If you are starving and you don't like sushi, but that's all the is to eat, you eat it.
