It's tragedy of the commons type shit. We're seeing this big in software engineering firms. Nobody wants to hire juniors anymore because you have to train them, and if you're the loser company that hires juniors and trains them you're basically just training juniors to be eaten up by Big Tech as soon as they become seniors, so it's just a "waste of money." Of course if everybody thinks this way (as they are) then nobody trains juniors and you have no senior engineers in 15 years. But executives can only think of the next quarter so uh who cares.

That's the next CEO's problem

These companies want to never have senior workers. They only keep them on by economic necessity. Senior workers are more expensive, so they really want to "de-skill" their workforce in order to decrease how much they will pay and make it so that they don't lose as much when firinh anyone for any reason.

When companies fail at this, which is what most of these will do, they reach a profitability crisis and either go bankrupt or get bought out by more liquid monopolies. If the big monopolies run into trouble they get the state to bail them out. Those that survive and try to be productive will need to pay a premium for senior labor and consider increasing levels of training they will fund. But this really depends on how much money they can throw around, which will be not much when this bubble bursts unless the fed goes ham.
