There are many “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?
