You have probably seen the pie chart below. (Thom's newsletter for Oct 4th linked to an article containing it.) But the problem in trying to understand it is that there's nothing equal about the wedges. They represent different amounts of wealth and different percentages of the population. It's hard to see that the average member of the top 1% has 480 times the wealth of the average member of the bottom 80%.
So I created the bar chart further below. Each pixel in the red, orange, yellow, chartreuse and teal represents 0.1% of the nation's wealth, and the pixels belonging to each segment from the pie chart are spread across the width of that segment's percentage of the population. (The top 1% is 1 pixel wide, and the bottom 80% is 80 pixels wide.) So now you can see the relative wealth of a member of each segment.

Note: "Wealth" (actually "financial wealth") was defined as net worth minus the value of one's own home.
