Income inequality exists in the United States. Is this necessarily a bad thing? Explain how our assessment of income inequality depends crucially on the source of that inequality

In a market economy, the distribution of income reflects the voluntary trades made by fully informed consumers and businesses. Those who provide goods, services, or resources that are highly valued by others will receive high incomes. Since all people differ in ability, education, preferences, and other factors, we would expect that people will receive different incomes. If the process that generates the income distribution is fair, many would agree that the resulting distribution is fair as well. Of course, if the process that distributes income is not fair--if it involves coercion or fraud, for example--we may very well be dissatisfied with the resulting distribution.
