The time-frame is the only hard part there. A majority of software developers in the US make six figures[1] (this is BLS reported data, so it's far more reliable than the self-reported data from somewhere like Glassdoor).
So the median salary for people actually working is just over $100K for all levels of experience. Which means that basically half of employed software developers in the US make <$100K. Yes, it's above the norm but less than a lot of people seem to think is easy to get.
