Vegetarians extend this in-group preference to animals, but not to plants. I've once watched an interesting series about how a Vampire secretly turned more and more people of a village into his own kind. Most didn't have a problem hunting humans after the change, but there was one character who chose to starve and die instead of drinking the blood of humans. That left a deep impression on me. So now I'm thinking, if you don't sacrifice your own life for your ideals, are your ideals even worth anything? If you want poor people to receive money, but don't want to transfer all your own wealth to them, aren't you just a hypocrite?
It's true that not everyone chases after money, but it's undeniable that lots of money equals power. If you don't partake in the competition, you can't win. You might succeed in deceiving yourself and others, but you won't wield the power of money. There are other forms of power, of course, like religion or other organizations, for example companies or countries. But even then, if you strive for the top of any of those, you'll naturally amass more money than the people at the bottom of the hierarchy. If you don't want the responsibility that comes with wielding such power, all you can really do is live in peace and hope that the powers that be leave you alone. You don't have any initiative and also no right to complain.
There's this saying that power corrupts, but I don't think that's the truth of it. Power only reveals your true character. Like the character from the story I mentioned, who received the power of being a vampire, but chose to starve himself to death.
