I’d argue schooling in general. Instead of being something you do because you want to and enjoy it, it’s instead a thing you have to do either because you don’t have the qualifications for a promotion, or you need the qualifications for an entry-level position.

People that are there because they enjoy study, or want to learn more are arguably something of a minority.

Naturally if you’re there because you have to be, you’re not going to put much, if any effort in, and will look to take what shortcuts you can.
