No YOU don't know what your ideas really mean

Socialism vs Free Market Capitalism. Whatever side you place yourself on I have noticed the way both sides will say "Yes you may think that but what you are advocating actually is... The government having total control over the economy and therefore your life or selfish corporation owners doing whatever they want without regard for the common man" I find this odd but I guess it should not be surprising. Each side sees itself as the champion of democracy, freedom, and justice. Therefore the other side must really want dictatorship, slavery, and injustice right?
