A socialist cares more about society and believes that wealth should be owned by the community as a whole. A capitalist cares more about their own well being and believes that wealth should be owned by the few. Over simplification but may help you decide which camp you are in.

I believe that the infrastructure that we rely on for transport, shelter, heat, water and health should be owned by the community and run for their benefit but I accept that responsible capitalism should be rewarded. Makes me pretty liberal in both senses of the word I suppose :-)
