The history of unions in the US is based around highly paid incumbents forming “good ole boy networks” when people [of color] started migrating from agricultural areas into big cities and accepting lower pay.
The history of almost every institution in America is that of non-blacks forming overt and covert alliances to arrest the progress of black people. For over a decade after the civil rights act, mortgage lending was organized to keep black people out of "white" neighborhoods. Shall we do away with the 30 year fixed mortgage?
