But sometimes you have to be less precise to make a more memorable point.
Oh, and I just thought about a lame joke: Yay! The ramen industry has 198 new costumers. Actually not that lame, what's the value-social-capital contribution to society from a YC employee, compared to 198 new Google employees? Who would politicians backup? Why they love Wal-Mart even if it decreases the local economy output? And yeah, I know the answer to the last question ;)
there is probably 20-30% of our workforce that isn't counted as employees
it always surprises me to see how many people's lives we touch (and i'm talking outside of all the users)
Fast forward YC 10-20 years from now. You often hear of Paypal or Google Mafia. My guess is that the YC Mafia will be orders of magnitude more powerful.
Successful founders will go on to invest into more startups or create more startups, hence creating more jobs, bringing out more technologies, helping more companies etc....
YC's just a butterfly, flapping its wings on its side of the globe...
