> What social contract? Companies have always been for shareholders.

You are not wrong, but the contract is/was metaphorical. For a long time people were able to make a living for themselves by studying hard (usually STEM) and end up with a career which payed off. That was the invisible "contract". Hell I went to university for things which seem like academic navel gazing, but I still got a good tech job on the other side. That's not the reality for a lot of graduates nowdays who take more practical degrees at masters and phd levels.

Again even if the literal statement is clearly false, it is the sentiment which matters, and this sentiment does not just apply to graduates. I think many just feel like working hard does not work anymore, especially in the face of housing, cost of living, job competition and social media flaunting the wealth of others.

I get the idea from my younger siblings, "Why try if you are already a looser."
