“I have conquered envy in my own life. I don't envy anybody. I don't give a damn what somebody else has.”

“It is not greed that drives the world, but envy.”

Munger made this famous, but he explicitly and repeatedly credited Warren Buffett — “I have heard him wisely say on several occasions, ‘It is not greed that drives the world but envy.’” The line is Buffett's; see the borrowed-lines section of /misattributed/.

“Envy is a really stupid sin because it's the only one you could never possibly have any fun at. There's a lot of pain and no fun. Why would you want to get on that trolley?”

“The world is not driven by greed. It's driven by envy.”

A shorter variant of the 'envy, not greed' idea; Munger frequently credited Buffett. Treat wording as approximate.

“They were having trouble with envy a long time ago. And it's a perfectly terrible thing to do, and how much fun can you have being envious?”

On 'thou shalt not covet'; he added envy is 'the one sin there's no fun in.'
