It does not require the equivalent to winning the lottery to get rich with a technology business. The odds are several magnitudes greater that you'll get rich creating a technology business than playing the powerball.
Being worth $4 million, and having a small business that generates $650,000 per year in profit, is rich.
Getting rich with a start-up in Silicon Valley, given the approach used there, is like playing the lottery. The start-up lottery you're referring to only exists in SV / SF. Nearly everywhere else, the fundamentals of having an operating business still rule - in that world, a lot of people get rich running smaller technology businesses. $50 million or $500 million rich? Nope, $5 million rich. Silicon Valley is mostly all or nothing, and that's what makes good outcomes so relatively rare.
