Wealth & Income Dispersion, Income Mobility, and Economic Injustice
There's a lot of trash being talked here and elsewhere these days about how income and wealth are distributed among the US populace, how these distributions are changing, what is causing these changes, and whether those changes are benign or malevolent. Beyond that lie the questions of whether, how much, and in what ways the fiscal policies of the Federal Government have affected these distributions in the past, and whether Government policy can or should try to affect them in the future.
My hope is to start a discussion of these issues that gets to the heart of our collective (i.e. political) choices about these matters, while avoiding a flame war based on misunderstanding and miscommunication. If there ever was a waste of energy it's a flame war where the opposing sides aren't even talking about the same thing. So here's my attempt to define some key concepts and terms and start the discussion. I'm sure I can depend on you to chime in with cheers, boos, clarifications, questions or elaborations.
Income dispersion is not the same as economic injustice. It should come as no surprise, and should arouse no moral outrage that there IS a dispersion in incomes received by individuals with different skills and talents. Low-skill jobs pay less than high-skill ones. Recent hires make less than workers with seniority. For the most part, differences such as these reflect the relative value of the economic contributions made by the individuals who receive the income.
There is nothing unjust or unfair about this as long as individuals have the opportunity to improve their skills and leverage their experience in order to move up the income ladder over the course of their working life. In fact, the potential for income mobility by individuals depends on the existence of such a dispersion of incomes within the job market. Terms like "income inequality" carry a negative connotation, but if there were no income ladder to climb, there would be no legitimate way for individuals to improve their economic well-being by their own effort. The existence of a wide dispersion of incomes in the economy is not, by itself, evidence of injustice or unfairness. If the dispersion of incomes grows over some time interval, that, by itself, is not evidence that the economy is becoming less fair or just.
Usually, at lower and middle income levels, most income is derived from employment (wages, salaries, benefits, bonuses) or entreprenuerial activity (profits, fees, commissions). At the upper end of the income distribution, a larger share is typically derived from wealth (interest, dividends, rents, capital gains). Younger people tend to get most of their income from employment, while older people get more of it from either their own accumulated wealth (retirement accounts) or from wealth invested on their behalf (pension funds).
Economic injustice arises when individuals are denied a fair opportunity to even get on the income ladder or to advance up it in proportion to their skill and performance. Defining, measuring and enforcing the meaning of "fair opportunity" is the heart of the matter. Children of wealthy and well-connected parents have an advantage in the competition for the best educational and career opportunities compared to children from families of more modest means and status. Is this unfair? Is it unjust? Is there a difference?
Income is not the same as wealth. It's only a little bit oversimplified to say that Wealth is the value of everything a person owns less the total of all the debts they owe. Income is how much they got paid last year. As a measure of economic security and well-being, wealth is more meaningful than income. A destitute person who wins the lottery, or a poor kid who becomes a sports superstar will have a large income for a brief period, but may or may not acquire wealth as a result. The scion of a wealthy family whose parents give him everything he wants may have neither wealth nor income of his own, though if he outlives his parents he will probably have both.
There are two legitimate ways to acquire wealth. One way is to save and invest some of your income instead if spending it all. The other way is to inherit it. Are wealthy people who got that way by earning a high income and investing it wisely any more or less deserving of it than people who got their wealth by inheritance?
