There are a lot of factors for the change in loyalty but I think the single biggest one is from when the managerial class went all-in on outsourcing. Those execs didn't care that they had a factory full of workers that had been loyal for decades, they happily sent those job oversees for a bump in that year's profit (and the resulting bonus). The people making those decisions didn't care that so many families, towns and cities were ruined by these actions, through no fault of the workers. Given that betrayal of the old social contract, why on earth would anyone choose to be loyal to such companies? Work loyalty still exists with individual managers or owners of small businesses that actually interact with their workers, but these days most workers correctly assume that most corporations are being run with little regard to anything aside from profit; and those workers act accordingly.
