Proportional representation is a form of capitalism

Capitalism where there is a state is good because it gives workers and consumers choice. It gives (landless) workers choice where to work and it gives consumers choice in what to buy. Choice is by definition good for the same reasons that capitalism is good. So then it makes sense for people who are in favour of capitalism to also be in favour of pr because pr gives voters more choice. Pr is a form of capitalism applied to democracy. It is inconsistent for people who favour capitalism not to be in favour of proportional representation.
