Greed is wanting more than you need and more than others have
I agree with everything else that you wrote Lois but I'm not sure about this one. The word greed carries a more malevolent connotation in my mind but according to your definition nearly every American ( even those we would define as poor) are greedy because most of us have more than we need for survival and more than others in places like the Sudan. A poor child in the south Bronx who has enough food, a roof over his head and a TV has more than he needs. I think that definition needs some tinkering.
Well, everything is a matter of definition, isn't it? I agree that wanting to acquire more and more for reasons that have nothing to do with basic needs is human nature. But we all have our definition of greed, don't we? What's greed to me may not be to you and vice versa. Of course, we all tend to see others as greedy and ouselves as not taking or expecting "too much," whatever "too much" means. To me, the worst form of greed is acquiring things with the intention of impressing others and thinking that having more and bigger and better things than most others makes a person superior.
It's a big subject that's worthy of discussion.
