I generally agree here, just beg to differ in two details regarding the US: the simplicity and the system.

What the US has cannot be called a system in European sense, and it cannot be called simple. Part of this complexity comes from the inherited common law, which is inductive - so all the forms of everything continue to live, in a perpetual attempt to see which ones serve the best, sometimes to the point that three generations later nobody remembers that these are still attempts. Which means there are dozen different kinds of courts, the laws aren't deductive (so you can't just have a definition of a type of an entity and then all subsequent laws just mention the entity in "applies to" - many laws are just partial, or have their own definitions of entities).

Also, there's no monolithic system of government; it isn't built axiomatically, it's very diverse, and various parts are maybe too independent for an European mind to grasp. Just take the dozen different police forces in charge of the same city - there's the sheriff and the marshal and the city and state and feds and university and ATF and the rest of alphabet soup. Specialized agencies for this and that, turf wars and whatnot. Then also there aren't permanent agencies across the board which would do the same things everywhere. In a European country if the government creates an agency, it reaches to the last village, or at least tries to; if the needs change, an existing agency may get more people and money to do more work. Here, there's no such system, there are individual programs, which generally start in only a few states or even cities (what I said about attempts), have fancy names and often their own administration, but aren't guaranteed to exist everywhere; they may be abandoned before they spread across all 50.

Add to that the level of federalism. The states have a lot more independence from federal government than in any European federation I can think of (not that there are too many of them left nowadays ;). I somehow can't imagine the Landtag of Schleswig-Holstein discussing whether to include intelligent design in the curriculum of their schools, or having their own typography on traffic signs.

There's just too much diversity across the board to call it a system (again, in the way an European mind imagines a system) or to describe it as simple.
