French psychology student here. Here it's pretty different: there are no campus, so most of us have 1 to 2 hours of transport to reach the university (some just live pretty close). I'm one of the rare dudes in my uni (90% of girls I think). Also, everyone can attend psychology college here (speaking from my experience).
But what you need to know is that :
- psychology is a vast subject, so some people might not be psychologists or therapists, but what they're doing required some resource 
- lot of them wanna know about their own psychological issues
- here, 60% of the 1st year students nail their exams and proceed to continue their studies
At the end, I kinda agree that a lot of people aren't that really into psychology.
You don’t have to get a job in the exact field your degree is in to make it worthwhile. Maybe they like the topics? >

Maybe. It's not really practical though. You make it harder on yourself to find a well paying job. And since you pay a shit ton of rent and everything why not use what you learn, if you learn anything at all and not just train just to remember writing an exam and then forgetting everything 1 day later >

I’m saying there is use and other jobs available with a psychology degree other than becoming a psychologist >

Like HR, coaching, maybe some marketing jobs would be happy to see it, or career advisors. And some workplaces just want you to have a degree, any degree
