I think there are all kinds of intrusions into private rights that make use of contemporary technology.

What's the point of being better than someone else?

What has to be done today is (1) large-scale conversion (weatherizing , etc.), (2) sharp change in transportation to greater efficiency, like high-speed rail, (3) serious efforts to move to sustainable energy, probably solar in the somewhat longer term, (4) other adjustments that are feasible. If done effectively, that might be enough to stave off disaster. If not, then we can give up the ghost, because there are no alternatives in this world, at least none that I've seen suggested.

It's roughly the case that if systems become too complex to study in sufficient depth, physics hands them over to chemistry, then to biology, then experimental psychology, and finally on to history. Roughly. These are tendencies, and they tend to distinguish roughly between hard and soft sciences.

As a health scientist at Columbia University, Les Roberts, pointed out, sooner or later people are going to be looking at a child in a wheelchair suffering from polio and will say 'the Americans did that to him'. So they continue policies which have similar effects i.e. organising the Taliban. This will come back to them too.

I don't see how one can "believe in organized religion." What does it mean to believe in an organization? One can join it, support it, oppose it, accept its doctrines or reject them. There are many kinds of organized religion. People associate themselves with some of them, or not, for all sorts of reasons, maybe belief in some of their doctrines.

American decline is real, though the apocalyptic vision reflects the familiar ruling class perception that anything short of total control amounts to total disaster.
