That went downhill fast. I'm assuming here that you mean income inequality. Just bear in mind that equalizing politics has been one of the greatest sources of tyranny in history (think Animal Farm; see Frankfurt's "On Equality" for some discussion around equality qua equality and the issues around it). The problem isn't inequality per se, but things like poverty or secondary issues like the power that money often buys. To say that "the system" is the ultimate source of our evils is a silly notion that fails to pin the blame on individuals. "Systems" (or I'd say, prevailing social realities) can make bad behaviors appealing, but morally upright people do not take advantage of such opportunities. Certainly, some social orders are better than others, and legal systems that punish and reward appropriately is very important, but thinking that a properly constructed "system" will eliminate all concerned evils by removing inequality is terrifying madness. Focus on the elimination of poverty instead. Inequality per se is irrelevant.

In Animal Farm, the source of tyranny was not equality, on the contrary; it was the failure of the masses to sustain the idea and to prevent the leaders from violating it. Orwell was still a believer in socialist equality, just not in the Bolsheviks or Stalinism.
