Wage discrimination won’t solve this - skewing it will create resentment and turnover in another location. If the workload is heavy, I would assume that there is understaffing. And I will emphasize again - wages depend on the reproduction of labor force, not on how much surplus value it brings.
I see you didn’t come here for an understanding of political economy, but to find justification for cannibalistic wage theft by business owners. Oh, well.
