It all depends on how specific one sees the statement of "paying for value created". One could also argue as follows:

If an employer wants the work done _from and in location X_, the location is part of the value created. If they want employees to work in location X, then they will have to pay according to location. If employees decide by themselves, that they want to relocate, assuming that remote working is possible, or that the employer has offices in the new location, then that is their own decision, with all the consequences, including getting more or less out of their wages in the end.
