True, but it only gets worse. The ultimate result is the destruction of the United States as a Constitutional Republic and the irreversible birthing of a North American totalitarian tyranny - either Marxist or Islamist. It only remains which ultimately and bloodily will prevail in enslaving us.
Great analysis, as usual, bray!
The republic already has a fairly strong centralized/planned "marxist" (equality of outcome - crony capitalism) flavor to it. I am not convinced that collapse of the established federal order results in either outcome you pose, however.
Before there was a US of A, there were independent states, and those still exist, albeit weakened by an overbearing federal government that disrespects and disregards the Constitution that created it.
When the time of chaos comes due to the federal government being unable to deliver what it is promising, and that time will come, it is inevitable, social unrest is still under the hand of state and local governments. I hope and pray that at least some of the states come through stronger and more free. The American dream won't die, even as it is now being suppressed and undermined.
I don't think violence is inevitable - in case you took "chaos" to mean that. Collapse of the dollar, loss of international prestige, massive bankruptcies, etc. can all happen; and the state and local police powers will be brought to bear. The strength of a country lies in the character of its people and its natural resources.
If the country is to be a harbinger of collapse of Western civilization (and that too is possible), I think it'll happen over the span of generations; much like it took a span of a few generations to transform the federal government into the massive, irresponsible an unresponsive entity that it is now.
