One might argue the socialism provides a greater degree of freedom by taking care of the bottom layers in Maslow's hierarchy of needs. If you don't have to fight for food and shelter on a daily basis, you are free to pursue greater things, and eventually find lover, happiness and self-actualization.

I think people often conflate socialism with fascism, but they are two very different things. Fascism can infect any form of government, Mussolini's capitalist, right wing Italy was fascist as well as Mao's communist China. And, currently, we have socialist countries that are very free, like Denmark and Sweden...while some capitalist countries are much less free, like China - currently listed as one of the Top Ten most capitalist countries, while still maintaining fascist policies with regards to free speech, human rights, and their 'justice system'.

Freedom doesn't hinge on the type of economic system a country embraces....it hinges on how much power the government applies to the control of its citizens.
