You are, of course, in a position to know what everybody on Earth needs.

What if someone wants to give $10 million away per year to worthy charities? Will you tell them they can't?

Or... what if someone wants to own something you consider wastefully expensive? Is it your job to tell them they shouldn't? Or is it wiser to adopt the position of humility and say "Well, it's their business, not mine, what they spend their money on"?

It's easy to be motivated by envy, even when we think we aren't. It's much better for your soul, and your peace of mind, to adopt the "let them" mentality, and not decide what other people, whose lives you know nothing about, need.
