According to Victor Davis Hanson, Stories of Imperial Collapse are Getting Old:
But this country is now in its third century and assurances that the United States is about through are getting old. In the early 20th century the rage was first Spengler and then Toynbee who warned us that our crass consumer capitalism would lead to inevitable spiritual decay. Next, the Hitlerians assured the Volk that the mongrel Americans could never set foot on German-occupied soil, so decadent were these Chicago mobsters and uncouth cowboys. Existentialism and pity for the empty man in the gray flannel suit were the rage of the 1950s, as Americans, we were told, had become depressed and given up in the face of racial inequality, rapid suburbanization, and the spread of world-wide national liberationist movements.In the 1960s and 1970s we heard of the population bomb and all sorts of catastrophes in store for the United States and the world in general that had unwisely followed its profligate paradigm of consumption; yet despite Paul Ehrlich?s strident doomsday scenario, the environment got cleaner and the people of the globe richer. And then came the historian Paul Kennedy, who, citing earlier Spanish and English implosions, “proved” that the United States had played itself out in the Cold War, ruining its economy to match the Soviet Union in a hopeless arms race — publishing his findings shortly before the Russian empire collapsed and the American economy took off (again).
In the Carter “malaise years,” we were warned about the impending triumph of “Asian Values” and the supposed cultural superiority of Japan, Inc., which would shortly own most of whatever lazy and ignorant Americans sold them — before the great meltdown brought on by corruption, censorship, and ossified bureaucracies in Asia.
