I didn't see a thread on this yet. Famous Internet comic Maddox attacks the myth that in the United States, women make 77 cents for every dollar men make. The video and article are in his usual style, and though I don't think his case is air-tight, it is laden with arguments and evidence to counter the wage gap claim. What's more, he also attacks womens' advocacy groups for inventing these claims in order to sustain themselves.
