How? US system is clearly majoritarian and yet it has themost upward distribution of privilege in th edeveloped world. By contrast, state socialist countries were ruled by minorities withthemajority opposing that rule, but they flattned the privilege hierarchy quite a bit.
I think what matters more is the internal divisions within society - the more fragmented and compartmentalized it gets, the steeper the privilege hierarchy, and the easier it gets to muster a superficial consensus on symbolic issues (e.g patriotism, foreigner bashing) to cover up that ineqiality.
