If you look at the historic context of military vs. education spending, I don't think it's a straw man at all to point the difficulty of raising non-defense spending. In fact, the difficulty of raising taxes in the US is just put in more stark lighting when in perspective of the amounts spent on the military vs. everything else.
I'm not saying state spending is impossible, just that raising it for non-military items is exceedingly difficult. That's not the only reason why the US university system is worse in x way than y country's, but when we're discussing public funding of universities we have to acknowledge the political and fiscal realities of trying to do something about it. I say that when accounting for those realities and the difference in public funding levels for education and other programs, it's no surprise that we have students in debt.
