Levels doesn't seem to track salaries for your average "mediocre" (see, work-life-balance prioritized) developer quite as well.
In Canada their end of year report listed some cities with median salaries of 100-130K USD, but I think most Canadian devs aren't on levels, and earning a bit less.
For example, the Canadian government pretty much pays software engineers between 40K-80K USD (even for 20 YoE). They're surely a massive employer, but they're not listed on Levels
Not that working for big tech or U.S. companies is that much more desireable, but it does pay a lot more, and those people are more likely to be reporting on Levels
