When you buy, say, a hamburger $1, are you buying the hamburger for a dollar...or are the restaurateurs buying your dollar for a hamburger?When you work for someone, they, in theory, pay you no more than you're worth. They bought your services for X dollars...or you bought their dollars for X services. In any case, you are even. You didn't make any money in the sense of a profit. Why is it that we pay taxes on the dollars we get...but do not have to pay taxes on the burgers we get, since, in theory they are of the same value and are exchanged as equivalent.
