What's funny is that small and mid-size businesses that Silicon Valley looks down on can generate IPO money.
Founders, senior management and investors can make vast fortunes when companies go public, but "IPO money" for rank-and-file employees is typically in the six and seven figures, and that's in best case scenarios.
A lot of small businesses generate net profits of six and seven figures annually. My SO's uncle, for instance, makes over a million dollars a year running a services business. So every year, he's banking more than many employees will make in one-off IPO windfalls. There are tons of business owners like him in this country.
Before I started working on my business full-time I earned about 5x what I make now (and that was over 15 years ago), but I'm much happier now.
