Over-generalizations like this are as predictable as they are annoying. Sure, it makes sense for some people to skip college. And maybe someone could even make the case that most people would be better off abstaining from higher education. But what if you want to be a researcher? A scientist? Someone working on the outer boundaries of knowledge in some particular discipline? Self-study is all very well and good, but…
But there are many degrees out there that I see as not very necessary to get. English, Art, History? If you want to be a teacher sure you need these, but you can get by on your self learned skill and knowledge alone.
People just need to make sure they're going to college for the right reasons. Because it will further their career not just delay them from it.
