On balance, yes I think university is worth it. Over the course of a working life, the university fees are a drop in the ocean and you only pay it back once you start earning over a certain amount.
Of course, if you are set on doing something that doesn't require university, then good for you. And of course there will always be successful people who haven't been to university. But if you're unsure or are open to different career opportunities, then university gives you more choices later in life.
