I have a liberal arts degree, and I've been a residential carpenter for the last 13 years. I guess the money I earn puts me in the middle class. Looking back on that time it's fair to say I've left a lot of money on the table by not seeking a higher-paying job.

I don't think it's arguable that a Google engineer will not make more money than a carpenter on my crew. The thing that bothers me about articles like this is the sense that technocrats like Andreesen assume their needs are everyone else's.
