That's not the point this article is trying to make. What someone has left after taxes is their own business. So what if others are left with more than you? People's expenses vary as widely as their incomes. Someone else may end up with 5 times as much money as you, but they may be supporting 10 kids or suffering an expensive chronic health condition that sucks up a large portion of their income. They may live in a higher-cost area or be running a small business (which means money left over often gets reinvested in the business). And maybe the other guys simply works harder or is in a career with high demand and low supply of candidates while you work at Wal-Mart. It is in no way fair for him to have to pay more simply because he has more.
