Despite the numerous issues with the american primary/secondary education system, I'd imagine you'd struggle to find many arguing that making secondary education free to everyone (qualified or not) wasn't a net benefit for the US.
It is my personal feeling that the entrance exams that used to exist as a barrier to secondary education were awful and unfair. Everyone should have a right to choose their direction, instead of being told you have to start a job/family. Based on the success of eliminating that barrier, I feel opening up university/college to everyone should be the goal of any civilized society.
