Financial products? Fintech is but a small portion of the overall software industry. Neither Google, Facebook, Microsoft, Apple, nor Amazon specialize in fintech, and the big 5 are as much a driver of high salaries as anything else. We get paid highly because, while software is expensive to build, it's basically free to distribute and so you have huge economies of scale where sometimes as few as 50 employees can make a multi-billion dollar product. And also, because software is hard to do well and there is so much platform explosion.
