And? You still haven't proven why the european model (or, in your chosen case, the french one) isn't working as well as the american one. You still haven't proven that easy access to education is a bad thing. You are still arguing without actually having data to prove your point (to wit: That a) there's a significantly larger amount of school graduates visiting university, b) that there's a shortage of workers available, c) that raising the bars for education would allow for better economic performance).
Also, you fail to take into account the very simple thing that, if we wanted to, we could do all that. We don't, because there's this common belief spread throughout Europe that education is something that should be free. We think it has worked rather well. Sure, we could do it like the americans. But why would we want to?
