Could it be for once useful not to be completely divided? Sure, rich people use and have used race, sex and so on to gain and maintain power but rich people are also composed, even if not homogeneously distributed, of different races, genders and so on.
Pointing fingers at rich white man helps in the same way as point fingers at rich Jews. It helps nothing but hiding the valid criticism of the out of control system we live in behind a hateful division of society.
