In the U.S., sure, university is expensive. The thing is, putting yourself $40-80k in debt(sometimes more) is more frightful on paper than in real time. People receive their degrees at 21-23 and talk of being in debt late in their 30's because they paid $50-$300 a month on their student loans. Honestly, if you're good with money and haven't been stricken with consumerism, you can get a job(maybe in your field, maybe not) & pay your loans off in 5 years easily.
The way I see it, University is a gathering of minds. Meet people, join clubs, make friends and connections; that along with the knowledge and social experience you'll gain in your experience will set you up for not having to live paycheck to paycheck or find yourself at a brick wall with no idea how you can get yourself to the next level.
