Capitalism doesn’t allow for individuals, alone or banded together in groups (parties, majorities, minorities, etc.), to vote on anything that would violate the individual rights of others. The amount of money you have or manage to raise for a political campaign is of little importance. It may “buy” you a federal, state, or local position—president, governor, county commissioner, etc., or a senate or house seat. But the constitutional checks and balances protecting our individual rights ensure that you cannot wield political power over others when you take office.
Consequently, the political inequality we experience under statism doesn’t exist under capitalism; no slim majority wields power over minorities, and no minorities wield power over other minorities or the majority. Therefore, money does not play a significant role in who gets elected.
