Fair; it's not for everyone - but that's really not the point.

The point is that no one really thought "22 year olds" were capable of making an economic impact before YC came along. Hence, someone with the simple idea to say "Hey, we should give 22 year olds this deal" created an employment impact on the economy as big as Facebook. The more people that come up with new funding models like YC that actually work, the better we'll all be.
