I think that one of the issues COVID-19 brought to light is that when push comes to shove (and collapse), most of the stuff humans are doing (at least in rich countries) is actually useless, unnecessary or wasteful of resources.

Before building the cities and populations up for 8 billion people, nobody stopped to ask, "What are people for?"

Instead, it was just left as an assumption that all countries should be competing to support more and more people in some nonsensical competition of power and wealth by extracting every possible resource from the planet. Liberal thinking humanitarians (not to be confused with humanists who took the burden of destiny from God and expected humans to take the mantle) used the increasing deaths from famines driven by the unthinking reproduction of overfed humans to pull on the heartstrings and "feed the starving" instead of saying, "Stop it!"

For every million saved, there was another opportunity to sell a million iPhones and TeeeVeeees.

Now we can't.

So, that's it then.
