You underestimate how quickly infrastructure rots out from under the incompetent. Historically, it generally seems like 80 years is the longest a society can keep coasting under it's own momentum.

It's become apparent we're losing speed. Soon some "equality" initiative will start butting up against enough pillars of society that things will collapse, the goal right now is to make sure it comes down on their heads not ours.

No one's getting away clean, but maybe we can collapse back to something that looks more like the 1930s than it does like 1984 or the bronze age.
