I know far more people who are making lots of money doing traditional, un-sexy businesses, and I can't think of anyone I know personally making money with apps, web2.0 etc.
The reality is only 1 in 100 people are likely capable of building a great startup (in the PG sense of "Startup") that succeeds - but there is a huge part of the population that can build out a brick and mortar traditional company.
To put things into perspective, On the App Store, about 3,000 of the 1mm or so apps are capable of supporting a developer in the United states with the Median US Income ($53,800/year).
