Everyone doesn't need to go to college, and I agree apprentice/trade stuff would be great for people who don't want to go to college.
Anecdote, but my half brother is apprenticing under his father in welding. However, both he and his dad get paid relatively low (no special certifications or whatever it takes to make good money as a welder). Also, I don't think he's learning cutting edge and highly desired welding skills, just basics. I think apprenticeship isn't going to be enough to put someone in a great position to learn a craft as a master or to make great money in a trade. Just as a degree won't guarantee success, neither will apprenticeship, though it is another path.
Where I work, for many positions I don't think a resume will be considered without a college degree on it. A bachelor's is the new high school diploma. To encourage apprenticeship, businesses would need incentives to do so. Why would they choose to apprentice people if there is a glut of college graduates desperate for work? It seems convincing business owners would be the key, and what incentives would those businesses have to do this? If businesses don't do it, who would? Colleges?
