There can't be 340 million separate Constitutions for 'individuals', for one, and a common national set of morals and principles for all under the laws, whether the mentally ill, assorted deviants, and psycho lawyers like it or not. Yell 'fascist' and other rubbish all you want, America's bourgeoisie had lost its capacity for self-government in the 1960's, due largely to 'Affluenza' and mindless narcissistic self-indulgence, which in themselves produce neuroses and pathological behavior common to sociopaths.
Your politicians very much reflect the people they rule over; all those pols and bureaucrats come directly from your own populations and have the same mentalities, they don't drop in from outer space and they aren't Red Chinese with lots of plastic surgery. IF they are corrupt amoral narcissists who only look out for themselves and fuck everybody else, look in the mirror; both 'left' and 'right' wing nutjobs are from the same cess pool. The 'culture wars' were lost in the schools first.
There is no quick fix, it takes generations, and you don't have that kind of time, much less even the will to do so.
