But in that case, you're paying people for a different bundle of agreed job duties in each case, where one important differing constraint is location. I just moved from NYC to Montreal. Same time zone, cheap to visit NYC, I can work legally in both places (and Canadians can easily visit NYC on business even without being American), etc. A remote employer shouldn't change my salary much based on that - if anything they should raise it if they already deal with Canadian/Quebec payroll/benefits, since NYC benefits cost them more, or lower it just enough to compensate for the added compliance and travel burden. But most would lower it dramatically.
