I know, it's hard to answer because the more you dig the more you start to ask uncomfortable questions about the fundamental nature of our economy and the emergence of varying degrees of wealth inequality... at which point saying when you should or shouldn't be greedy seems arbitrary.

If there is an economic event that cuts of a huge chunk of the population from being able to meet basic needs, even though regardless of money the resources are there, then clearly an adjustment is needed.
