Research indicates that lesbians tend to make more money than heterosexual women. Over at Big Think, Marina Adshade attempts to demystify the phenomenon:
Sure, lesbian women are better-educated on average, are more likely to be white, live predominantly in cities, have fewer children, and are significantly more likely to be a professional. But even when you control for these differences, the wage premium is still on the order of 6%.
It is fascinating when the data starts looking like the majority is being discriminated against. Is it wage discrimination, though, or is there an economic argument for why lesbians are getting paid more?
