Eugene it looks to me like you averaged the peaks. I think there is more area under the right half of the peak, I would think the average is closer to $350k-$400k. The definition of income and tracking it is also pretty hard to comprehend. According to the IRS lottery winnings are income and capital gains are not taxed as regular income, even though you work for the latter and not the former. I am always amazed when I hear “average household income is ??k”. I suspect it is actually higher than measured as a lot of income does not seem to get measured. Gross income and net income for me differ by a factor of 2 so that obviously makes a big difference when stating such ratios.
