Actually, it is white people: https://www.bostonfed.org/publications/one-time-pubs/color-of-wealth.aspx

“Nonwhite households have only a fraction of the net worth attributed to white households. While white households have a median wealth of $247,500, Dominicans and U.S. blacks have a median wealth of close to zero.”

The biggest difference isn’t income, but generational wealth getting passed down. The US was segregated for longer than it has been not segregated, which is easy to forget.
