If people wish to donate money to foreign causes they should be allowed to do so. But in cases where outsiders are supported against our own kind this is clearly a moral evil. But egalitarianism as a political programme he opposed on two grounds. Firstly it was unjust,as it relied upon compulsion, encouraged envy and inevitably levelled people down since levelling them up is impossible. Secondly, equality undermined the natural order of things, nature being hierarchical.
Social equality is against nature.
Economic equality is against nature. At worst, ambitious elites use equality as a pretext to reallocate resources to themselves. At best,well-intentioned people see equality as no more than a benign aspiration. This is perhaps the greater error. Abstract principles,however appealing, cannot be applied directly to solve real political problems.
