The United States corporate culture has reached a failure mode of game theory. The average corporation is allergic to spending any money on training and has pushed all of the costs onto labor.
They hope that some other moron will take up the costs and then they can poach the trained employee for cheap, while any corporation that does actually train feels like they should get the employee for cheap afterwards instead of compensating the employee at market rate.
Simultaneously the average corporation refuses to do something like have a contract with the employee for X years of labor at a set rate in the exchange for the training because they are also allergic to not being able to change their minds and lay off half their staff the next year.
This would be a place for the government to come in and force everyone to pick the good square on the prisoner’s dilemma, but yet again, our corporate culture is allergic to regulation or cooperation.
You can still get through a winter or two by eating your seed corn so I guess we’ll just continue barreling down this path.
