Your post is very naive. In the UK, some universities are so dependent now on foreign students paying high fees to break even, that it has been widely reported in the media. And in a few EU countries, polytechnics have been upgraded to university status (at least in their English-language names) in order to attract fee-paying students from the developing world. Finnish polytechnics, for example, run whole marketing campaigns in the Indian Subcontinent in order to get people to come and pay those sweet, sweet foreign-student fees.
