In 2003, the average salary in tech was $69,400.

By 2017, the average salary had risen to $92,081.[1]

While that might seem like a pretty large payrise, after adjusting it for inflation, you come to a clear conclusion that over the last 12 years, salaries have stood basically still. You can point to people getting $120k+ as a first year employee at Google, but salaries like that are massive outliers. Average developer in america earns much less.
