I have never been able to figure out why people do not take the American system of government as their model? As the ideal model. I men if you run s series of experiments with different molecules and one of them simply blows up in your face, the other turns into a foul mixture of mud, and etc,  until you get to one that works and gives you beautiful colors in a stable compound--then why go back to the other models? I can only explain this in one way. When it comes to politics, people are insane.

See the essay of Michael Huemer which goes into this in great detail and that essay itself is based on the original idea of Bryan Caplan. 

[You might ask why I bring this up. The reason is I have been looking at the writings of Trotsky and his My Life after his expulsion from the USSR for anti revolutionary propaganda. At any rate that was article 56, and then later article 58/10 that he was expelled under. And in one sense that was correct. [The USSR was not formed to be a dictatorship but rather a rule of the party of working people, and that party had voted legally to expel Trotsky.] He worked to put the labor party [the proletariat] into power. The idea was that only people that were actually doing physical labor deserved a right to vote. No one else mattered. And if one did not work, she did not get a welfare check. She was shipped off to prison. And that party of the proletariat voted to have Trotsky outed. And in some ironic way that was exactly what he was advocating.--permanent revolution. So if you have a revolution, and then you keep on revolting, that means you are revolting against the revolution. [So to speak.]

[You might suggest that people are always looking for utopia. What ever they have that works is not good enough. They have to find the perfect system. But to do that they first have to work to achieve the goal:"Down with the System!"] [As per the 1960's]. And this explains most of what people complain about concerning the USA. The issue is never the real issue. The main thread of continuity is anything that the USA has done is always shown to be evil. The idea is not to improve anything, but rather to kill the USA with a thousand wounds.  Not any one alone would be fatal. This is the reason for the continuous attacks on anything the USA stands for.
