Simple answer: Because socialism denies individual rights. I have the right to mine metal and make a widget, I have the right to sell apples, and the "human rights" of others, who may be starving do not supersede my rights, no matter how badly they hurt.
dont you know, freedom means everything is free
No, it doesn't. Freedom means being able to have a free and clear title/ownership of something, without some do-gooder socialist trying to steal it.
