As long as some people believe all man are created equal and human rights are universal, then those people will always exist and humanity will eventually go down the drain as it happens in the film "Idoicracy".
Well most countries run a sort of meritocracy system, where the best in a field are the ones used. However the system isn't perfect and sometimes you end up with a fool running a country, and we have TB and GWB. Human rights are universal, the best person for the job, has nothing to do with being equal, that would be some sort of bizarre for of communism, that is even more improbable/impractical than Marxism.
Kudos for slipping in the idiocracy reference, that's not as unlikely as people think.
