A core tenet of the "dark enlightenment" mind-virus that has taken hold of the valley is the idea that civilizational decline/collapse is not only inevitable but imminent, so they don't really mind getting a bigger slice of a smaller cake, as long as they are in charge[1].

However, they also are getting citizenships from other countries or buying pacific island bunkers: just in case.

1. The collapse inevitabilitism absolves them of any guilt when their actions make the world worse, since "it was going to happen anyway"

It's also pervasive. The weirdest thing in the world is watching someone I know who works for a big tech company and moved to the States suddenly wanting to get a New Zealand citizenship "just in case".
