It's also way harder in the US to go back to school as a working professional. Most people can succeed in university, but the window to do it with the least struggle closes after you're adulting hard, have a family, etc.
For most people I can understand why this would be true, especially if you have a family. For me, however, it was the exact opposite. When I first went to college I was abysmal at it and soon dropped out. After a few years of work experience, however, I went back and finished my degree while working full-time. Despite having much more to juggle I did vastly better at college my second go-around. I think having better time-management skills, being emotionally more mature and intuitively knowing that I needed that degree in order to get a better job all worked "against" it being more of a struggle, in my opinion.
