Why Salaries Vary by Region

Pay follows the value of output and the local price of labor, not fairness. Wages cluster high in dense, high productivity metros with industry depth, think Bay Area software or Zurich finance, and lag where living costs and productivity are lower.

Labor mobility smooths some gaps, but housing costs and licensing rules lock much of the difference in place. Remote work created a partial arbitrage, so many employers now pay by zone, cutting pay for moves to cheaper areas.

The practical rule is simple: never compare your salary across regions without adjusting for rent, taxes and childcare, because the same title can mean very different lives..
