"Governments, if they endure, always tend increasingly toward aristocratic forms. No government in history has been known to evade this pattern. And as this aristocracy develops, government tends more and more to act exclusively in the interest of the ruling class-- whether that class be hereditary royalty, oligarchs of financial empires, or entrenched bureaucracy." ~ Politics as Repeat Phenomena, Bene Gesserit Training Manual, Children of Dune, Frank Herbert

Seems to me the best way to evade this pattern is to entrench the working class, aka the Majority, as the ruling class, thus ensuring the government will tend toward working in favour of working people, but that's just me
