That doesn't make your point. There's more to the story (as always) and lots more to the economics of it than I understand.

To put it simply, the logic that it's wrong to store a good for benefit means we should also say it's wrong to save or invest. So yeah, if you have any equity in anything and if you don't spend your entire paycheck each week, you're hurting people. The truth is the opposite. Competition of "selfish" behaviors is fantastic for people because it results in more abundance and variety than otherwise.
