I am really happy that you make 420k but I guarantee you that there are plenty of developers who make more than 220k. (I make more than that and in my know plenty of folks personally who make that amount) One easy to way more money than this is to work in finance space in NYC.
I guess working at an hedge fund, HFT, or doing some C++/ASM may be the only way to earn such salary.
Indeed, I am 24 year old programmer, 2 years out of a top CS program and I am making $280k (100% cash) slinging C++ for a small quant hedge fund.
Silly question. If you are making that much in NYC, how much are you paying for rent?
