How much do you know about Black History in this country? Blacks were legally discriminated against and were permitted from ownership.
Furthermore, when blacks finally were able to able to own homes, we saw things like the Tulsa race massacre where whites went in (with the help of the all white city government) and burned down their homes and business, along with taking their land. And that's only the worst one. Entire towns have been taken in at least 50 occasions.
So, is inheritance a direct cause of what Brian Flores is fighting, no? However, it is absolutely linked to the systemic and institutional racism that African Americans have seen throughout this country's history, leading to a DIRECT lack of accumulation of wealth.
