Credentialism and signalling are well established. At a broader level it's the old 'correlation vs causation' chestnut. Policymakers notice that people with education earn more, and decide that people should do more education so they too can earn more, but it mostly fails because it wasn't just the education that holds them back. Meanwhile, in a world where everyone is forced to see high school through to graduation the value of a diploma is diminished.

In tech, some companies are increasingly willing to captialise on this by expanding their hiring pool and benefiting from snapping up workers that other companies don't want to hire. So there's some hope it seems that we can break free from the credentialist world that we're in right now.
