This chart from Mother Jones' Dave Gilson and designer Mattias Mackler is a very powerful illustration of the enormous wealth gap between white and non-white households:
The median white family is almost 20 times richer than the median black family, and 74 times richer than the median Hispanic family. This holds up even when you look at relatively advantaged black and Hispanic families. As Danielle Kurtzleben noted a couple weeks ago, the typical white family headed by a high-school dropout is worth more than the median family headed by a black or Hispanic college graduate.
And regardless of race, the median household has seen its net worth decline compared to 1984 levels; households at the 25th percentile of net worth have seen their wealth decline by more than half. It's worth noting that the typical household's net worth comes mostly from home equity; if you exclude primary residences and any debt associated with them, the median 2010 family's net worth falls from $77,300 to $29,800 (61.4 percent). That's real wealth, but it's not exactly liquid and doesn't substitute for more flexible, and higher-performing, types of savings.
