The first part of that is just not accurate at all. The US was a catalyst for a giant leap forward that infected the entire globe with productivity, prosperity, & ideas about individual rights, resulting in a greater reduction in poverty than at any other time in human history. The US is the safest place on earth if you remove from the stats the authoritarian leftwing cities that have banned guns. It is the corruption & abondonment of American ideals that is the problem.
But the American experiment WAS flawed & contained the seeds of its own destruction. The aim & ideas were basically correct, but the seed of legitimized theft set us on a path destined for corruption & empire & collapse. A force funded organization cannot be controlled or held accountable. Taxation has to end unless we want to repeat all the same mistakes again. Hopefully Bitcoin's nature helps in that area.
But guns are completely necessary for the existence of a peaceful society where the weak & vulnerable are not forced to live at the mercy of the strong. A man in a wheelchair with a gun is just as dangerous as any other man with a gun & that keeps those who might otherwise prey on him in check. Guns are equalizers.
