The primary threat to freedom and justice is not greed, or hatred, or any of the other emotions or human flaws usually blamed for such things. Instead, it is one ubiquitous superstition which infects the minds of people of all races, religions and nationalities, which deceives decent, well-intentioned people into supporting and advocating violence and oppression. Even without making human beings one bit more wise or virtuous, removing that one superstition would remove the vast majority of injustice and suffering from the world.
