The point is that you as a company do not care where your remote workers are except perhaps they need to be in a timezone close to that of whichever office of yours they are working most closely with.

If you can pay remote workers what would be a good wage in El Paso or Tulsa or Boise and that is sufficient to get you enough good workers from such places to fill your needs, you don't care that it is not enough to get workers from Boston or Minneapolis or Chicago because you don't specifically need workers from Boston or Minneapolis or Chicago.
