I wholeheartedly agree with your opinions.

You have written and explained in easy-to-understand paragraphs, the very reasons why some people seem to mindlessly pursue careers in college without stopping to think about their usefulness in the real world:

1. The social aspects and experiences associated with attending university.

2. Becoming an "intellectual authority" on a subject, sometimes just to say they have majored in such and such; but sometimes having a paper that says you know "X", doesn't mean you will be good at "X".

I also liked your advise: invest in yourself! entrepreneur your way into success and carve your own path toward a profitable skill, spot on.
