> Get rid of all immigrant workers and the industry will collapse, because your graduates need to pay off a huge debt that immigrants don't have.
You went to university because you decided (in expectation) the present value [1] of the future earning were worth the college fees and the opportunity cost of getting a university degree. So, don't complain about the debt: by your decision you computed that this decision was worth it. The only thing that you need to complain about is yourself that you did a wrong calculation for such a life-influencing decision of going to college.
