the whole thing is a lie. The reality is asian families in the USA have a far higher income than many white men.

Also female engineers employed by IT companies now get 117% of the income of your average male employee. Why you may ask, well because female's make different life choices to males leading to fewer female engineers even though 60% of university graduates in the USA are female. So what companies do to make themselves look better is pay the few female graduate engineers they can hire a wage that is higher than a male graduate. Where is all starts to fall apart is because of the life choices problem for female employees. Males generally work long hours and will spend more time at work due to the fact they generally don't get pregnant nor have a preference of putting family before work. Climbing the greasy pole takes time, the more time you spend climbing it the higher up you go. If you stop climbing the greasy pole to have kids or go home early to see the kids then your fellow workers are not exactly going to stop climbing the pole just because you have left the building. So when these women come back to work they find themselves on a lower income than their fellow workers who started climbing the greasy pole the same time they did.
