>"Isn't that what they are doing in high school?"

To some degree yes but a much more limited scope than what's available at the university level. I don't think most public high schools teach humanities, political science etc.

Two year schools are basically vocational schools. I don't doubt there is a place for that but I think they are different products.

Unfortunately, having a two year degree with experience still gets your resume thrown in the trash at the first step of the funnel. Ask me how I know. Doesn’t make sense fir most jobs but there it is.
