Could you name where Socialism was a complete success? Don't point to the Scandinavian nations as they've come out and said that they aren't Socialist nations, but rather Free Market Capitalist nations with social programs. I seem to recall that one of our Northeastern states tried it and failed.
True Socialism means taking over all the means of production and ruling by the gun. Any businesses that would reject the socialist policies in a Socialist nation would be pushed out of business by force. In the instances where Socialism took over the means of production, the first debacle in each case was mass starvation as governments don't have the faintest notion about farming and distribution. Under Socialism, political opponents aren't allowed, thus ends Democracy, for to be a Democracy, opposing views must be allowed. Under Socialism, the freedoms enjoyed under the US Constitution are ended. Freedom of speech....gone. Freedom of religion....gone. Freedom of the Press....gone. Right to bear arms for your protection....gone. Due process....gone. Right to live in your own private home....gone. Search and seizure restrictions....gone.
