1) Despite an appearance of being "left leaning" (according to polls of faculty political sentiment) they continue to gatekeep education behind prohibitively expensive tuition that is out of reach of lower economic strata without crippling debt, and have simultaneously struggled to produce graduates whose economic differential easily makes up for that expense and lost work time.
2) They enjoy a tax free status while receiving significant tax money despite many failing to grow their student bodies in tandem with the growth of the US population, leading to people questioning whether they deserve those benefits as institutions that serve the public.
3) There is a sentiment that basic literacy and numeracy of graduates has dropped over the last decades outside of a narrow area of studies, because of a shift to a model where students are customers buying a credential instead of getting an education.
(These are all interrelated, of course.)
(Yes, yes, there's vapor-ware, and useless products, and certainly "fake jobs". Those existed in the '40s, too, and in any other time period or economy you care to look at.)
In my view, the problem is that white collar workers stopped thinking of themselves as Workers. Any of us who rely on a company for a paycheck (and, perniciously, in the US for health insurance) aren't Capital, even if we make high salaries. Maybe we're aspiring to join that class - we'll hit the startup lottery, or FIRE, or our IRA portfolio will go up forever - but we ain't yet. (That's fine, by the way: I'm using Marxist terms, but I'm not a Marxist. Pursuing financial independence, and the real - even if remote - possibility of attaining it is what's made the US such a dynamic economy.)
However, allowing our aspirations for wealth, or the relative comfort of white-collar jobs, to lead us to identify with the political goals of Capital - or worse, to adopt an elitist attitude towards people who work in what you call the "real economy" - is what's got the US into the mess we're currently in. That's the "genius" you identify in the present system, and the origin of the cruelty within it.
In reality, we're all Working Class (well, 99% of us are - although that proportion is way out of whack on this board, of all places!), and we need to (politically) act like it.
