I am not familiar with other countries but I can tell you that in the United States there are similar problems. Many people get University degrees in things other than science and engineering only to find out there are no jobs in that field. They end up working at very low paying jobs that have nothing to do with their degree even though they are highly educated. Also the cost of even public universities is very high. Most people have to take out lots of student loans to graduate and have enormous debt when they are done.

Many foreign students do come here on student visas to get degrees but I have no idea how they afford it. I assume they come from wealthy families but I do not know. There maybe programs that help them pay for it. I know there are some programs for the medical field that if you work a certain number of years in an inner city or a rural area after you are done with college part of it is paid for.

Sorry I can't be of more help.
