Those that can self-educate effectively are also ones that would thrive in a proper high education system. Unfortunately, we're turning them away for various reasons (financial, lack of flexibility, etc) and filling rooms full of people who are there just because they were told to be there. It's quite horrendous, people in their 3+ years and they're still just going through the motions for the paper.
If you're not there to network and find a job, you're the odd one out. This idea of treating these institutions as places for continual higher learning is just not the norm.
It's an interesting predicament, more education for everyone is better, yet our designation of colleges/universities as the "last" required tier has stunted many people in many ways.
