But salaried work also needs things like a university degree (mostly). What I'm worried about isn't so much that there will always (or for the foreseeable future) be "skilled" and "unskilled" buckets of labor, but that there's this self-reinforcing loop that creates a permanent underclass of gig workers.
Lots of skilled jobs don't need college degrees, employers just require them because it's convenient filter that doesn't have much of a downside for them.
