And it certainly isn't better than all the others.  It has strengths and weaknesses in comparison to other large nation-states, and those are a matter of taste.  There are small nation-states which have systems which are vastly preferable to the U.S. system, in my opinion, but they are generally special cases.  Iceland is not too bad.  Norway is fairly tolerable.  I could almost stand Scotland.  Singapore is rather decent.  Chile, quite nice.  Conceivably Paraguay.  But then I've not lived there long enough to see the worst aspects, to judge how deeply they disturb me.
