Second, a hyper-achievement culture that has forced parents to feel as if they must 'keep up with the Joneses' or they are failing their children.
There are two big issues that startups in Austin face that I think stunt their collective growth.

I now live in Palo Alto, CA working at a startup called Flipboard.
