And to the "outsiders" from outside US, it should be written that 40-45 percent is taken away as taxes. So, if someone is making a total comp of 200k, it is basically 120k. This should be written in bold on this website.
Actually i would say, instead of having these charts which compare total comp, its better to have a survey on how much people save after rent, taxes, and basic living expenses (not including loans etc.)
