In an analysis of the relative income, or relative consumption, hypothesis, it is shown that if the ratio of agent i's consumption to agent j's consumption enters into the utility function, a tax on labor income may increase welfare for all agents. If pretax wage inequality is low, all agents will unanimously be in favor of such a tax. Thus there will be a tendency for taxes to be high in societies where pretax wage inequality is low.
