Don’t listen to the daily news == Don’t worry about the massive program of deprivation, destruction and death carried out on your behalf to secure the aforementioned “unprecedented wealth”
But (an important "but"), first, while resources are limited, there may be enough for all of the humanity (probably; at least that's what I think, maybe I'm wrong), so by using some resources to "just exist" you're not killing someone else because they still have some resources to just exist as well - so in terms of individuals this logic may, maybe, apply to billionaires but not to people who "just exist"; and second, it's not all that simple, and while there's some "grain of truth", the real world is a bit more complex.
Exactly what I think, personally.
