I am not a socialist. All be told, I am an anarchist. I believe in personal liberty, which does not exist in any system, really.
My argument is that capitalism does not work. Neither does socialism, or any ism for that matter. In order for them to work, everyone has to agree to go along with it, if not, it fails.
One grain of sand can spoil the ointment.
My beef with capitalists is that they get all gung-ho about giving more money to billionaires, while ripping apart the underclasses, without making any effort to understand the causes of poverty. They just tend to blame immigrants.
