Bob goes solo to discuss a recent Twitter controversy, in which opponents of a proposed tax argued that unrealized capital gains couldn't possibly be a form of income. Bob cites both Austrian theory and corporate accounting practice to respond that all capital gains are income, which is not to say that they ought to be taxed. The dispute is important because understanding the definition of "income" sheds light on the role of market prices in guiding entrepreneurial action.
