I just went to Asbury Park, NJ about a month ago. It was all local highschool/college kids. I go to an ice cream shop in Brooklyn by a park - all highschoolers.

I think it just depends on the location? But also yes - if I'm worth my salt, why would I take these jobs over higher paying internships? At 19 I was able to land $25/h jobs in tech. Maybe we should rethink the pay scales in terms of sustainability. Unfortunately we live in the US where short term gains are the sole motivator for most companies.
