Or they can enjoy the fact that they have regulatory capture and change the regulations, as has been seen historically.
For practical observance: Denmark pays a wage to university students. The function of this wage is to make sure the students can focus on their studies, instead of having to have a job that demands time from them, which would lower the quality of education.
Students also need housing, which the private sector provides in the form of "student housing", which requires you to be a student in order to live there. This "student housing" has a rent that is usually, approximately right around the student wage - thus meaning the student needs to take a job in order to afford things such as "food" and "electricity". This state of affairs occured despite regulations.
