There are many[Broken link] “info” graphics about income inequality in the United States. Measuring the combination of wealth and income that most humans care about is inherently tricky. If you measure wealth, then a computer programmer in his early twenties making a large quantity of money looks poorer than a 65-year-old janitor who has been dutifully saving for retirement for 45 years. If you measure income, then an 80-year-old former CEO might look poorer than a middle class worker. A lottery winner, who won 10 million dollars and then spent 6 million before he realized he owed 5 million in taxes, looks poor by either measure, except, for that year when he won the lottery where he looks richer than almost everyone else.
Is there a graph that looks at the distribution(among the population) of total income earned over one’s life? It would have to examine people of the same age, say 20, 30, 40 … 90 year olds.
Is there another way to measure wealth/income distribution that avoids these issues even better?
