There are dramatically more software developers today in the US than 25 years ago. 1.6 million with a median salary (before benefits) of $109,000. So the field got a lot larger in terms of labor (2-3 fold depending on how you want to count it), while simultaneously paying so well - a particularly remarkable thing. Those jobs tend to come with good benefits as well, including nice health insurance (which is obviously extremely expensive in the US).

Granted, this is peak software developer and we're just starting on a downslope for the profession (both in the US and globally).
