So instead rely on public education which fails many students in delivering a quality education, or, having given up, just pass them to let them figure life out once they graduate.

It's not necessary that corps own the education, but they they have schools within a school to deliver the education that they are expecting from new graduates.

Public education is what made those great companies you fawn about.

Public education is also something you are responsible for as a citizen. If it is shit, it is so because you let it be. Assume your responsibilities instead of hoping for "enlightened" corporate lords to do it for you, peasant.
