A thing I never understood is, what happens if, let's say, I stay in a HCOL area until I am doing interviews (eg Switzerland) and then when hired I move back instantly to a LCOL area (eg Albania): what happens now to my salary? Do I get a cut just because I decided to move? And what if I am a digital nomad and know I want to change nation in which I stay every x months?
Even if, why not just legally live of your uncle who has an apartment in San Francisco, while you defacto live in South Alabama. With remote jobs I don't understand why someone living in a cheaper City should get less.
You're not getting less, the world doesn't have a global currency with fixed price. It's all about earning power. If a company has an office in Alabama, and another office in San Francisco and another in Accra, Ghana. Employees won't expect to be paid the same, so why should they expect the same because they are remote?
