There is no system that works perfectly, any one of them is subject to collapse given the right conditions. Democracy was the greatest experiment in human history, of course our first attempts would fail. America set itself apart from other democracies and may have what it takes to survive the eons but I think America's decline is the globalists showing us how America can fail by forcing it to. They're showing us right now all the worst case scenarios that must take place to bring the power structure to it's knees.

The only way they could win at this point is by nuking us, but even then, our founding fathers gave us the best possible system
