There is a bias there in action: we are assuming that the entire world is like this thing we just happen to be thinking about.

It is not.

Even if it were just a minority, there are plenty of people outside "this thing" that will profit from the ((putative) majority's) anesthesia. Or which at least will try to set the world on fire (anybody remember the elections in USA a few months ago? That was really dumb. But sometimes a dumb feat shows that one is alive, which is better than doing nothing and being taken for dead. Or it is at least good-enough peacocking to attract mates and pass on the genes, which is just an extravagant theory of mine that I'm almost certainly sure is false. And do not take this as an endorsement of DJT). I'm not being an optimist here; I've seen firsthand the result of revolutions, but it may be the least-bad outcome.
