We do. Every year discovering yourself is a year you're not productive. Those cheaper university fees come from taxes which you need employed people to pay. I'd argue the US system is fairer: people who enjoy university education pay for it. In Europe, people who got in trade and never thought about getting a university degree are paying for those for get them.
The unfairness in the US system comes largely from the fact that, depending on what kind of family you come from, college may be very easy for you to attend or very difficult.
Stateside, as NPL rates increases with the nominal prices of attending, this becomes less true on top of that it is assumed that future taxes will support these increases well into the future.
Tuition is pretty cheap in Canada-- definitely as compared to the States. I'm actually at university to do just that. I'm in a math degree while I get my certs. I'm getting a minor in Latin, because learning the language is literally on my bucket list. I'm having a pretty good time, I'd say.
The cost of college forces some people to also argument for better revenue opportunities and better fit for future jobs, because otherwise burning through ungodly amounts of money just to be a better rounded person would be a hard sell.
In countries where university are cheaper nobody bats an eye at someone going through the cycles just for the sake of it, purely to learn interesting things.
