I live in a society with free education for all, up to and including university. To make that possible, there are a limited number of seats, and the number is based on the needs of society, and on our government's budget. The seats are allocated based on testing, but there are multiple ways to "test into" a seat, i.e. "you missed it this time, but go do another two years of pre-university and you might get in later".

This is the best we can hope for: a transparent system, with clearly defined multiple pathways, and a limited number of completely free seats at the education table.

Also: one thing which other systems miss is different maturity. If someone is bright but at 15 does not see the point of studying and prefers to smoke with the stoners, fine. At 18, get a job in retail, and perhaps at 20 the light will go on and they will realize that there's a way put of retail hell and they are smart enough to test i to university with night prep classes.
