I dont think it is as simple as "willing to pay an extra 1-2k per month". It is with junior engineers w/o families. Once you have families, living closer to the job is way, way harder, esp for tech jobs concentrated in expensive cities. You cant just share a room with a friend when you have children. Also, things like schooling become considerations -- in NYC for example, you arent even guaranteed a seat in your local school (you're guaranteed a seat at "a" school.) It isnt surprising that SWE salaries ballooned in expensive metro areas and there are constantly "shortages" -- the huge premiums either go into super-expensive family housing near the city, private schools, a pied-e-tierre in the city, or some other acrobatics
Interest wage increases are going to decrease wage increases by softening the labor market
How many people are willing to pay an extra 1-2k per month to live closer to their job? How many of those people are the people you want to hire?
