For young people with no real financial obligations that's somewhat easy to accomplish.

For people in the midst of their lifes, working a regular job, taking care of a family, it can be very difficult to juggle all these obligations at once.

Because even when university is "free" it still requires you to invest time.

That's ever so true. I've been to university over several periods earlier in my life. The first time there were fees but they were manageable by most students (as the Government provided reasonably heavy subsidiaries). By the next time the government had changed and a more enlightened one came in and made all fees (except student union fees) free.

This was great for a time until work commitments forced me to stop before I'd finished. Then a little later another government reversed it all and it even went much further - the new fee structure went from free to like $50,000 or even double that for some degrees. Thus, my lack of time caught me out big-time.

That said, had I had the slightest notion what was going to happen then I'd definitely have managed to find the time. That's for certain! (I'd not learned the old addage don't put off until tomorrow what one can do today.)

USA: If you’re rich and not particularly interested in the topics, you to to college to meet people.

Some Euro: I’ve met many a person who continues to “study” to keep the numerous benefits.

Many people just don’t care. That dosen’t stop me from saying my idealistic, and unlikely idea after a word like “should”.
