I'm not convinced the employers know that. At least not the ones that ultimately control hiring. Granted, I'm not CS, I'm in the Mechanical Engineering world and it seems like a similar issue has existed (for possibly different reasons) for the last decade or so. That goes double for the skilled trades that our work heavily relies on. Companies don't want to spend the time and money developing new talent, they just want to find already developed talent.

They may throw some money and lip service at some school or community programs, but they don't really take on the responsibility of insuring a sustainable ecosystem of people in the industry. Like a lot of issues it's the Prisoner's Dilemma. I'm not sure how it is in other parts of the world, butat least in the US, with some rare exceptions, I don't see people and companies changing from being selfish to trying to maximize the benefit for all without changes in policy, and the likelihood of that is well........
