I don't know about that. My model of Taleb has him pointing out the many dangers of entrepreneurship, and the myriad biases which lead people to underestimate the risks of starting a business--survivorship bias et all.
Actually, I'm kind of wrong -- but kind of right. Pg. 80 says "You are the source of our anti-fragility" in regards to entrepreneurs. Basically it's lots of small fragililities which tend to create anti-fragility - hundreds of entrepreneurs trying to create businesses and failing over and over again, causes economic growth.
If you are able to live cheaply, and learn a lot doing something risky, you are being anti-fragile.
