One of the ways I know that we're in a bubble is the frequency with which I am now meeting intelligent young men who sincerely and with every appearance of unselfconsciousness tell me that they want to be founders of startups as an alternative to joining the workforce and learning their trade.
This is really the only comment I have a problem with. Do they really say "as an alternative to learning their trade" as if the workforce is the only place to learn?
