During the gold rush few really did find their fortune. But the ones who got really, really rich were the guys selling the tools (to dig). Who's selling the tools today?
- Landlords and real estate developers (who are making a killing in the current bubble)
- B2B companies targeting startups
- Professional services (lawyers, etc.)

All jokes aside, you're right, the analogy has some flaws. Or maybe the tools supplier hasn't emerged yet. Talking about a big opportunity here!
And we know who's getting really, really rich ... and its not 'people selling tools'. Its Google, Apple, Facebook, AirBnB, Dropbox, Stripe, MongoHQ, Heroku, Parse ... i.e. successful tech companies. Its not an unknown.
