> What evidence do you have that significantly more than 10% of engineers earn more than $400K? What evidence do you have to the contrary? Compensation data isn't typically shared openly. Well-paid engineers have no reason to share their pay figures and create animosity or worse problems.
I have no strong evidence to the contrary. I'm trying to learn the truth. The previous commenter made claims about the distribution of comp. No doubt they had reasons for believing that claim. I want to know their reasons so I can update my own beliefs. I have made no claims so I don't understand why you are asking me for the answer. I'm trying to learn the answer! :)
There are also past threads on reddit and hacker news which include anecdata that points to such compensation being reasonably common, but again that requires believing anonymous internet people.
