> what type of developers are pulling that kind of income?

So, the subset of developers who make this much money basically amounts to "The senior engineers, at top tech companies, such as google/FB/ect"

Which.... is less unlikely than you'd think, if you are talking about the democraphic of users who read hacker news.

500k is still definitely up there, but making even something like 250k, at any of these top tech companies, as a mid level engineer, is completely standard. I'd expect anyone who has 5 years of experience, at these types of companies to be making at least this amount.

So, within that context, the people who are making twice that, would be maybe the team leads, or possible even a bit higher ranking than that.
