"In a Capitalist democracy, the poor have exact the same voice as the rich...with one difference. By definition, there will always be more poor than rich. So the poor will ALWAYS have more political power in a democracy, because there are more of them. More votes.

So Capitalists only have as much power as the poor allow."

I don't believe you have even tried to deny the following concept:-

1) There are 2 people, person A and person B
2) Person A is rich, Person B is poor
3) In a capitalist society, a person with wealth has more options avaliable to him/her because the options of certain services, certain goods and certain lifestyles cost money
4) More options means that person has more freedom, the freedom of choice.
5) Therefore person A has more freedom than person B
