I think the sentiment is very U.S. specific. The US seems to have higher education system with some peculiarities. They have the best universities but also some shady ones and it can be expensive.
Obviously if you just want quick vocational-type training, you don't need university level education. But then you should not be the one having problems with procrastination or self-discipline either. Most students in universities are there because they would not study or learn difficult or uninteresting subjects if left on their own. You also need to learn to communicate verbally and in writing with your peers. Knowing stuff but not being to able to communicate and work with others leads directly to low level jobs.
