When work went remote, it took coastal paychecks with it — and a disproportionate number of them landed in Idaho. Software engineers, consultants, and executives brought San Francisco and Seattle salaries to Boise, Sandpoint, and a dozen towns in between, rewiring the state's income map almost overnight.

The infusion has been a boon in obvious ways, seeding new spending and, in some cases, new businesses. It has also introduced distortions, as households earning coastal wages bid against local incomes for the same finite housing stock.

The effect is most acute in small towns, where a handful of high earners can move an entire market. A mountain community that once ran on tourism and trades now finds a parallel economy of remote professionals living alongside it, connected mainly by the housing they compete for.

Whether the arrangement is stable depends on decisions being made far away, in the return-to-office policies of distant employers. Idaho has imported the income, but not the control.
