It is the fault of the electorate who have devoted themselves to the bestial philosophy of eating, drinking, drugging, copulating, evacuating their bowels and snoring. A people adopting such values have no time for good government and will soon lose their lives, liberty and property. As proof look what was elected President. Look at the flood of Third World emigres.
What you say is beyond debate. The American people may be amongst the most perverse, ignorant, corrupt and morally decrepit people in the entire history of civilization.
Of course, that is not ALL the people but on balance it is impossible to the nation today in any other light.
Whose fault is it to be born with an sub-100 IQ? That is, who gets to choose their parents? You? The only reason anyone is reasonably intelligent enough to be sufficiently able to engage in political philosophy has nothing to do with environment, and everything to do with genetics.
This has been well known & understand for millennia: the lower classes simply were not allowed to participate in the body politic. So too was this country's initial foundation based on the same exact principle; only tax paying land owners were allowed to vote and/or run for office.
So who instigated universal suffrage? What was its ultimate goal? Well, I think we can reasonably surmise that we are in fact witnessing the results of this strategy.
Tyrants can rule through overt power, or they can be clever and use the tools of psychology. Via control of media, it is trivial to shape, form and control the thoughts & opinions of the vast number of people who are not equipped to understand or engage in rationale processes.
Blaming the electorate misses the real culprits.
