Instead of income this graph focuses on personal net worth. I found the pie chart at Metrics 2.0, depicting the share of personal wealth by region in 2000.
Average wealth amounted to $144,000 per person in the USA in year 2000, and $181,000 in Japan. Lower down among countries with wealth data are India, with per capita assets of $1,100, and Indonesia with $1,400 per capita.
