Well. here in South Africa education up till 16 is nominally free, though there are a lot of grade 10 leavers who are unable to do more than write down their name, possibly read a little, can count up to 10 possibly, and who expect that they should go to university, and that they should pay no fees, do not need to actually learn and that after 4 years they will automatically get a degree, a government job, a car, a house, clothing and food ( and of course booze in large amounts), all for just being there.
When you have "students" saying that they want things, and that they should not pay for anything, and that they find things not to their liking and burning them, vandalising them, and generally making it impossible for those students who are paying, are studying and who will graduate with a valid degree to do anything. All things that are a result of them never actually being taught anything in school or at home.
