You have a choice whether or not to have jobs/devote time to your family. They don't. You may claim that you are forced to take a job because of your financial circumstances, and hence you don't have a choice, but what about them? Those who are cash strapped can't even go to university because they can't pick up jobs to pay their way through. You seem to be suffering from a case of selection bias, foreign students appear to be favoured because those who *aren't* don't go to college and aren't covered by your survey.
