Thus far, the only way I've found to do this is by changing jobs. I've been somewhat successful at it, I think, but that somewhat puts a limit on how frequently I can do this, and I'm not fond of the negotiating.

The world would be a better place if people just paid people what they were worth. If we could start having more honest conversations about salary (e.g., talking about salary, and comparing salaries should not be taboo…), I think it'd go a long ways.
