Total comp for my college hires averages around $150k.
Total comp for my career level ICs averages a smidge over $200k.
My top 10% have total comp in the $350k neighborhood.
The very few folks who are at the staff/principal range (depending on which companies titles you're using) are taking home $500-800k (mostly in stock). If we consider attrition, it's probably only 1 in 150 of the engineers we hire who ever hit this tier or above.
The levels.fyi info seems pretty accurate to me. Their estimate for my personal role is within 2% of my actuals.
I believe you're confusing top-line revenues and profits available for the tradesman. As it stands, you're asserting that your plumber makes approximately 14x the average plumber in America, and 10x the average plumber in San Francisco. This is unlikely to be correct.
In a similar vein, Apple takes in over $2,000,000 of revenue per employee, but Genius Bar employees are not taking that amount home. I mention this solely because it uses the same reasoning evident in your initial claims.
So yes... I think the average plumber in SF is making about $70k/yr. (so ~$300 per day worked, or $200 per day).
