I have to point out that using the “average wealth” to compare black and white people is a classic example of poor use of “average”. While a bigger number looks better for writing, you shouldn’t be using this. Even among white people there is a large difference in wealth between “top 1%” and “bottom 50%”. I’m fairly sure that if you remove “top 1%” from both black and white people, the number will move much closer to the income difference in Seattle than the mystical 1700%. This lower number still shows that there is a problem, but if this number isn’t used, any attempt at a solution will fail terribly since the starting point is wrong.
