In Europe all countries have tuition free universities, in Denmark people even get a government stipend of ~1000 USD/month by the government. And yet, there is availability on most programmes (like computer science)

It seems like the market powers do not apply for American universities? When tuition (demand) surges, it should be profitable to expand supply (new unis, added seats on programmes, hire more staff).

Regardless, the supply seems quite inflexible?

Though it is convenient to blame the government for supporting the ones most in need (young people starting their careers) it seems to be more appropriate to blame structural issues that inhibit the creation of supply – which is also very anti-American.

They can go do whatever they want to themselves. Either tell me what cool new tech you want me to try out and what problems we might want to solve soonish and I'll see which of those and how it might be applicable to or you tell me you want to build <whatever it is> in whatever tech I think will get me there best and fastest. If you know so much, do it yourself. Oh you can't? Well then STFU (not you you but that proverbial manager type above you that seems to know so much)
