You've got an odd view of how neoliberalism came into being and you've framed working class ideology as a rational choice most people have made, rather than a response to the circumstances they've found themselves within.

There were American working class uprisings and nationwide unionizing efforts. There were violent revolutions. Those efforts weren't broken up by offering full time jobs and a living wage. In fact, those wages, weekends, and 40 hours were the victories the uprisings achieved. Much of them happened over 100 years ago, so I do understand they've kind of faded to the background of American history. Bloody Harlan, the Pullman Strike, various skirmishes around the Midwest, and most of all the Battle of Blair mountain in 1921, where 30,000 cops and soldiers were sent to arrest striking miners in Virginia. Afterwards with the coordination of power among federal law enforcement agencies, the creation of the FBI, and increased police funding nationwide, any sort of worker movement was put on the back foot and have remained there ever since. Union membership has dramatically declined since the 1970s, and at one point 10% of CPUSA members were FBI informants.

Most working class Americans now are either too beaten down to care, are professional managerial class, or they're some odd combination of worker with a petite bourgeois mindset with home ownership acting as a mental substitute for business ownership. Of course they won't listen to Marxists, they're either beaten down to the point they don't believe anything better is possible, or they've convinced themselves their mortgage and 401k gives them skin in the game.

Professors with new, more vague rhetoric about oppression were an adaption to the boundaries of acceptable rhetoric and were by and large a way to express a more or less liberal worldview using some language adapted from Marxism.
