I do the same type of eye roll and I think it still applies here. Unless "the whole industry" create a salary cartel, the free market will adjust for this salary imbalance quickly.

If there's a guy living in a black neighborhood that does the same job as a guy from a white neighborhood but for less, who would you hire? So will everyone, and the salaries will eventually match.

This is even more true in a world of mostly-remote workers where social interactions are reduced.
