Gonna chime in here because I'm a career counselor. Most trades are always in demand.
I'm going to compare 2 trajectories from a purely economic point of view:
University: 4 years for an entry wage. 6 years for a better one. The next 10 years you pay off student loans.
Trade school: 2 years, then you work as an apprentice. You are making money while you learn. School is paid for soon. After apprenticeship you make much more money. After red seal you can make excellent money all around the world.
So
4 years to make an entry-level wage and massive debt
or
4 years to excellent wagesn (typicaly much higher than 6 years of university)
And 2 of those years you earn entry level wages. Small debt is quickly paid.
Of course not everyone can do trades. They are physically demanding and require specific kinds of smarts. And people might have deep curiosities or like me a calling. It's not always about money.
I can't tell you how many people I've met who studied for a prestigious career that they end up hating. They (or their family) want to be a lawyer or engineer or doctor. (Dammit Mom, I always wanted to " × " )
Maybe retirement will be hard. I just put myself at work.
