I was making 400k/year at one time, I also had a few million dollars (that I earned by being "working class" in SV) invested in the S&P500. Which is why your argument has no merit. I could have stopped being "working class" with a 400k/year salary any time I wanted and lived from my investments but I didn't.
I kept being "working class" in SV and I ended up growing my compensation package to nearly 1 million dollars a year. That's what being "working class" in SV can amount to. But please try to convince me that I should take to the streets with my working-class brethren that work at Starbucks because I'm being exploited by the elites.
