I went through an unconventional learning path - I didn't think I was ready for post-secondary straight out of highschool, so I worked first. After I felt I was ready, I went. Everyone told me I was crazy and I needed to go straight to post secondary, but as a result I was able to figure out what I wanted to do, and gain some discipline and perspective while I was at it. I did well in post-secondary school, far better than I ever could have dreamed of in highschool.
At College I couldn't believe the number of people straight out of highschool who slacked off and wasted their parents' money. I was involved in a student drive and I got to see it even more firsthand. Asking students about why they were interested - "my parents want me to go". "I don't know". Those were the most common answers.
People mature at different rates, and expecting everyone to be ready for College right as they enter adulthood is madness. Some people need some life experience, some people will never gain those skills and should take alternate life paths. To be clear, taking an alternate life path can be risky, and the one I took is not the one for everyone. I think we just need to take a critical look at what we're asking of late teenagers and young adults.
