Given than in Europe we have no debt but we don't do any of those things either, I'd say you're looking at something else.
And I can only speak from my own experience, but people here do seem to do more of the things I noted. With a month off a year and, frankly, knowing you won't die in a gutter if you lose your job, you can spend more time on music, writing, whatever. But that's pure anecdata.

The theory is, if your mortgage interest rate was X% but some other investment like the stock market had much higher returns, a sophisticated investor might want to take the money they would have spent on repaying the principal and instead put it into that better-performing investment, then after 20 years pay off the mortgage principal with said investment.
Post-financial-crisis rules were put in place that mean banks actually have to ensure you're _making_ that higher-performing investment.
That softens the issue, but doesn't make class mobility easier.
What does this mean? Asking as a European that might be missing something (compared to Canada for example) but doesn't realize it.
From what I understand, you can get out without debt here (norway). No tuition, low fees for books and things. Government stipend doens't need repaid, but you can take out a loan above that (common). Then move up north and work for some time. 10 years, I think? And I'm awfully sure that some countries won't have as much debt in that time simply because living expenses are lower and some folks are able to live with family while going to school for the 5-6 years it takes to get a masters.
It hardly matters on the distinction, though. It isn't like tuition in the US covers living expenses. Even if you are able to live in student housing, you don't get housing all year in many places - you might need to move yourself and your stuff out for anywhere between 2 weeks and 2 months. Whatever your loans for living costs are, at least they aren't higher due to tuition.
