> This is also why workers who unionise can be paid more - the union has power over the employer. I'm not convinced a union wouldn't adjust pay based on location though. A lot of times they already adjust pay by tenure, and other factors that don't affect job performance directly. Right now employees at tech companies do have power. If you get an offer that is adjusted based on cost of living, you can say no, and there are plenty of other places hiring.
