Wait till you fill out a federal tax return. In many cases if people know how to use the system they can go to multiple agencies every month and get financial assistance. Unless someone is really keeping track of this or a person is being investigated, it is hard to say how much someone's income actually is. It can be Educational assistance in the form of free books, free tuition, or free daycare while you are going to school. There is all kinds of free money. Women's homeless shelters give you a place to stay and that is income also. Free food from a church that is income. Church gives you money for room and board that is income. Money for medications or meals at the end of the month that is income. Not many people actually can keep track of all the handouts.
Even with all that, it is hard to justify that someone making minimum wage makes as much as someone making $60,000.00 per year. Partly because often the well employed person is donating to a pension plan and also they and their employer are also doating to SSN. In fact probably a person making $60,000.00 will get over $10,000 in basic deductions if they have a typical 4 person family. Plus they may also get deductions for student loans, financing a house, Daycare deductions, Hope Education Credit, Lifetime Earning Credits, etc. Usually $60,000 in income will only amount to about $40,000 in income after deductions on their taxes. In fact for a family of 4 this only equates to 2 parents both making around $30,000 in income. That is just barely enough to survive after House payments, house insurance, house taxes, Phone bills, Car payments, Car insurance, Medical insurance and Co-pays, Gas , Electricity, Gasoline, Food, Clothing, etc.
