I'm sorry but this is a wildly inaccurate way to portray the data. This image is portraying not the cut that every group gets, but the wealth that the average individual in that group gets. These individual averages per group are then added up to 100% and then everybody gets a slice out of that 100%.
To show you how this is inaccurate say we did this with 10 people. We have 2 groups. Group 1 has 9 people who average 1 dollar and then group 2 has 1 person who owns 2 dollars. In that example group 2 has 2 dollars combined and group 1 has 9 dollars combined. This would mean the groups own 18% and 82% of the wealth respectively. But according to how this comic portrays it, as per Capita, the pizza slice of group 2 would be ⅔ of the pizza and group 1 gets ⅓ of the pizza, which is not accurate at all to how the wealth is actually distributed.
Using this per capita metric is highly misleading if we are to use it in that way. The top 1% in the USA in actuality holds 32,5% of the wealth in the USA which would create a totally different pizza than the one in the comic.
