Socialism, in its effort to not only believe that all individuals are equal, but to put this belief to practice, appropriates the resources of the productive for the benefit of the unproductive. In so doing, socialism not only punishes the productive for the crime of being productive, but oppresses the productive in the name of social justice. Since intelligence is one of the factors that leads individuals towards greater productivity, socialism punishes the most intelligent twice. It forces the intelligent to live under the laws of the unintelligent and then appropriates their property. Thus, not only are the intelligent more oppressed under socialism than most other individuals, they are also without the means to put the product of their labor to intelligent use.
Communism takes the final step towards oppression of the intelligent and productive.
Communism attacks, as well, the essence of individuality. Communism assumes that not only are we all equal, but that anyone who is distinct must be altered and forced to become indistinct. This alteration is facilitated by the use of re-education, institutionalization, and imprisonment. Viewing the relative productivity of societies under each of these systems, we can see that there is a direct negative correlation between productivity and the leveling of the individual. Applying this observation in the opposite direction, a society based upon the assumption of inequality of attributes among individuals should be the most productive.
