You think billionaires are hoarders because the shares they own become worth a lot of money when they build successful companies?

[TheOtherHobbes]

Circular definition. Number go up = "successful".

A non-hoarding economy would look very different, be far more exciting and inventive, and wouldn't be staging an ecological suicide run.

It's like playing cookie clicker except the higher your number goes up the more social status you and power you have.

[cryptopian]

And like cookie clicker, once you're watching the number going up long term, it's hard for your mind to accept a point at which you have "enough".
