Here's a short one.
A.) Capitalism does not promote freedom, and limits choices. It is the opposite of true freedom.
B.) Capitalism is better than collectivist style societies, and people are allowed to run businesses, purchase things, propety, work for an agreed wage, etc.
C.) Capitalism exploits workers, and people are left with few choices. Corporations run government, wage slavery etc.
A little all over the place, but it's a start.
