A tuition free university, University of Helsinki, is what Linux came out of. Free CS classes. A star was trained there.
The mentality of "you can't train stars" is bogus...it's more "we don't want to invest anything and want everything handed to us free and easy, and if we don't get it that way we'll complain about a shortage of stars"
It's great that it's been deduced that organizer labor is behind this article, and thus it's not neutral and has a hidden agenda. I'm sure someone who takes a 6% stake of high-growth companies for $14,000 is completely neutral with no hidden agenda. Also it's false that "none of these programmers are unionized". Programmers are represented by unions such as the IAMAW, CWA etc. It's possible 3 person startups have no union representation, but that's not out of the norm.
