You're dreaming. Nearly all the very wealthy and powerful are kidding themselves they're philanthropic and charitable, or have some other self-serving vision of their motives.

If anything around here is puerile, it's this notion that there's a powerful group planning to kill off most of humanity so they can rock on with the resources. Also that they control everything, like (you say) adults control the playground (long time since you were a kid ;)).

Which does not mean that, if circumstances led that way, those who have wealth and access to powerful networks would not defend their interests.   That could of course mean grabbing scarce resources for themselves, while weeping crocodile tears. Or backing an authoritarian rightwing populist movement. It's been seen before.

But let's stop with the comic-strip villain paranoia. It isn't going to get us anywhere.
