Should tuition fees be charged?

Providing an education for everyone is an undoubtable necessity, as it is recorded in the millennium objectives. However, what is doubted is to what extent that education must me free or provided by the governments. In most developed countries, the debate is placed on universities, where tuition fees often prevent people from taking courses.
On the one hand, tuition fees must be charged. Recent statistics show that nearly seventy five percent of people joining free online courses give up without finishing them. That cannot be allowed in universities since they, unlike most online free courses, have to fund a structure of salaries, equipment and investigations.
On the other hand, everyone with the proper academic performance must find it possible to join the university without compromising his future with university credits. A recent study in the United States has proven the failure of that model due to the decrease of wages and the difficulty of finding a job nowadays, even with a university degree.
So the solution could be to charge the lowest tuition fees that universities can afford or to charge high fees but offer also not-to-be-returned scholarships to every student who fulfills some academic requirements because, as I once found written on a desk of my university library: “what if the cancer cure is locked within the mind of someone who cannot afford tuition fees?”.
