I feel the need to say btw, because I overthink things and do need to remind myself too, there's an important difference between Greed and Gluttony:
Greed is hoarding a resource, only taking and never giving, it is not always about money but it tends to be about Power over others. The point of Greed is the resource is locked away, not for hard times but to just have More than others. Greed is what results in attempts to push minimum wage lower when you already can't pay to live with the amount given. They have the resources to do things, but they want to cut every corner they can because free is not a low enough price.
Gluttony is not 'greed but with food', it's overindulgence. Someone who is gluttonous could very much share, but are the type to eat until they are sick, or gather money just to spend it All on things they don't need for the rush, or intentionally take more of a drug than they should to feel the effects. Gluttony tends to be rather self destructive in this way.
