At least the freelance rates of today are about the same value as in the early 2000's, for the typical enterprise job.

I used to work as a freelance around 5 years ago, and I still receive some recruiter emails with occasional mention of the going rates.

It's the same as 5 years ago or less, which is the same since I remember in the early 2000's.

The rates took a hit with the 2008 crisis and stagnated since then. I think the golden age was somewhere in the mid-90s, where developers got paid really well.
