@engineer,
Have you searched Engineer? The reliable studies show wage disparity in the US is pretty small (much smaller than the political conventional wisdom) and even that is not that definitive.
Engineer, I would hope that you could look objectively at the data without being spun by the politically correct narrative. My understanding is that the wage disparity, when controlled for life decisions and career, is between 3 and 5 cents per dollar, and even that could be explained by factors other than inequality.
