Your egocentrism is showing, USAian. I don't even know where to begin dismantling your bullshit from how awefully absurd it is.
tuition for prestigious education out of reach of the common person
"Prestigious private education"? Are you joking? The people who take private higher education are effectively ridiculed, not to mention how private schools/colleges are always lacking – e.g. back in the day, when I compared my curriculum (actually prestigious public university) with all relevent private alternatives, they'd always be one year or more behind, which also means they'd finish their course with a huge gap in knowledge.
in many countries there’s a modest fee the government will pay out
Here in Brazil you can get upwards of two minimum wages. How is it that Brazil can afford this, but apparently the US couldn't? Besides that, yes, you may need a side job – that's what non-abusive internship/trainee positions are for. You work a few hours per day at a relevant position to your minor/major to get cash and relevant experience.
They come back at you in the form of decades of tax rates.
Except those decades of taxes ALSO pay for my healthcare (excellent, btw), bicycle infrastructure, to maintain parks, to protect local fauna and flora, for libraries, etc etc
