How rich is the U.S.? Economist Branco Milanovic, in The Haves and the Have-Nots, gives us a really interesting answer.
The poorest people in the U.S. are richer than most of the higher income individuals in other countries. Specifically, the poorest 5% of all Americans rank 68% in terms of world incomes. In other words, our poorest are richer than 2/3 of the world (p. 117).
The Economic Lesson
While Dr. Milanovic is looking at worldwide income distribution, we can also look at income distribution at home. In the U.S., our national income comes from wages and salaries, rent, interest, dividends and profits from businesses that are not incorporated.
To picture our income distribution, please think of a pie as the total national income and then individual slices as the proportion that different groups receive. That would mean that if total national income were $1,000 and a society had only five households (people living together), then if every household earned $200, distribution was equal. By contrast, if one family earned $800, then, because $200 remained for everyone else, there would be considerable inequality. Recently, the top quintile of households in the U.S. earned close to 50% of all income. This quintile approach for representing income distribution was developed by statistician Max Lorenz.
