I think compensation for developers is seeing inflation rates in the double-digit percentage points measured in USD. Might be even higher than 20% annually over the last 2 years or so.

Edit: I'm talking senior devs here. I think the stats are skewed by people who take a 1-week boot camp, then accept a job for $80K. I think there are lots of those. And they pull down the average salaries for "devs". But, ask them to exec into a pod, reduce memory, or increase performance...and they look at you like you have 2 heads.
