It’s a Volunteer’s Dilemma: why train juniors when you can hire the juniors other companies trained to become seniors?

Maybe companies should provide some sort of incentive for the juniors they trained to stay with them. As it is, the obvious and rational choice is always to leave for another company that will pay you 25% more whenever you feel undervalued.

I think pensions used to be that incentive.
