This is pure speculation, but I think there's probably a large variation in salaries in the 90/10 split of senior/staff+. The majority have decades of employment with the same employer rising up from junior/graduate level, whereas the others joined to bring "modern tech" experience with them to help execute a revamp. Most devs are probably in the top 20-30% band making tech a relatively "normal" (but good) salary in the local region. I could be entirely wrong though :)
