Economist Arnold Kling writes on his blog:
Back to Larry Summers, I think that education reform is not going to come from the college Presidents of the world. I think it is going to come from the bottom up, driven by the people who want to learn and by people who have innovative ideas for assisting them.
I think that at some point the best educated people will be self-educated. People like Ben Casnocha, who left college because I presume he felt it was slowing down his learning. Ben does not sit around at home, by any means. Every time I check out what he is doing, he seems to be in a different country.
I think that long before policy makers have figured out how to get everyone into college, college will have become obsolete.
