I started to notice that any racial group democrats target with the racial rhetoric always seems to end up worse off don't they?

Median Household Income, by race

135,000 - Jewish Americans
126,705 - Indian Americans
85,989 - Russian Americans
85,424 - Chinese Americans
76,665 - Canadian Americans
65,777 - White Americans
63,179 - -- Median American Household Income --
46,073 - African Americans
38,000 - Mexican Americans
49,963 to 28,745 - Native Americans

Bolded are the groups liberals have targeted over time.
Unbolded are the groups that have avoided being targeted by liberal race-politicking.

I could find this info for modern groups, does anyone know of a source over-time?
