To be clear, I don't think most people expect that either -- but I'd argue that most entry-level jobs today are just a big endless cycle of unskilled labor staying long enough to get fed up and moving to the next dead-end job, with the companies moving on to the next as well.

In general, I'd argue minimum wage jobs aren't anymore a stepping stone to some sustainable good job; they're basically viewed like consumables by companies. Even someone with a decade of experience, say, at several retail stores or restaurants, can't expect to be offered a position making $50,000 a year plus benefits just for having done his job well every day. By contrast, a dedicated factory worker with a decade of experience 50 years ago could expect to have advanced somewhat, and would expect continued advancement. Today everyone working in retail, restaurants, etc. all know that if they're going to do any better it's going to be by leaving that sector, via learning a trade, going to college, or perhaps founding their own small business. All things which were good options in the past too, but advancement was once a realistic expectation too.
