If so, that's quite different from what we have here. Public universities here in Brazil are among the best universities, and whoever manages to study in them doesn't have to pay a cent. It is completely free of charge. There is, however, a huge problem. The number of people interested in pursuing a degree has increased exponentially, but the number of vacancies made available every year has not. It all comes down to scoring high in an yearly admission exam, roughly equivalent to the SAT (except for affirmative action, nothing else is taken into consideration... GPA, for example, is absolutely irrelevant). If, however, the student doesn't manage to join a public university, there are many private universities, with highly varying prices, willing to admit new students, with nearly limitless vacancies, generally with no entry barrier other than being able to afford them.
Since the government didn't want to substancially increase spending in public universities, and since private universities saw the opportunity to make a huge profit, about 15 years ago the government started promoting student loans at low rates for the poor. The number of students making using of this loan reached it's peak in 2014 with around 700.000 students. Ever since then, the number has decreased. If I could guess as to why, I am going to attribute it to the economic decline and the arrival of a cheaper alternative: education at a distance, which we refer to as EAD. EAD offers online lessons (generally at low quality) for a MUCH cheaper price (up to 10x cheaper, and I am not kidding) and the exact same graduation degree. EAD is not avaiable for every course though like law school and medical school.
