That would be people you'd need though, not people that get "produced" in larger numbers than desirable. A million more engineers will be great. A million more art history majors not so much.

If every manual laborer had an engineering degree I bet a ton of it will get automated really quickly.

If every paper pusher had a computer science degree I bet a ton of it would get automated really quickly as well.

When liberal arts majors do low skill work they start clamoring for low skill immigration so they get people they can manage.
