While, let's be clear, administrative bloat in academia is a very real issue, pointing to that as the true root issue is far more nebulous. Student loans being made non-dischargeable by bankruptcy meant that universities could afford to raise tuitions because lenders would be happy/ier to fund those loans because they will get their pound of flesh, even if it takes decades longer than designed.
Taxing the extremely wealthy basically does nothing to decrease the property values of this class of people en masse, and decreasing their property values en masse is precisely what it would mean to make housing more affordable for more people.
"But CHILDREN will SCREAM here!" shouted one such lady at me when I dared express my opposition against her petition, which demanded a stop to a "megalomaniac" plan to build approximately fifteen apartments half a kilometer away.
"You were a child once, too," I said.
"Sure, but I was A GOOD BEHAVED ONE, NOT LIKE TODAY'S BRATS!" at that time, she was positively screaming as well.
M'kay.
The situation in the US may be different, but the few YIMBY blogs and articles I have read mostly described their efforts as an uphill battle against progressive politicians who were certain that development leads to gentrification and gentrification is bad. Given that the YIMBY movement originated in California, this may just be an aftereffect of Californian politics. But in general, it is blue cities and regions that are known for very restrictive zoning policies.
Neither restrictive zoning, nor the administrative bloat in academia that caused tuition to skyrocket, were lobbied into existence by people like Bezos and Musk. They are result of tireless lobbying of relatively unimportant people seeking their own little rent.
