Socialism is undesirable due to its potential consequences.
* It would lead to envy, mutual invective, and discord among citizens.
* It would cause a decrease in productivity as individuals would have no interest in exerting their talents or industry.
* It would result in a levelling down of all to a like condition of misery and degradation, violating the natural rights of mankind.
