You misspelled RAPE/WAR or whatever. The point is, anything is good if you end up on the good side of it. But what happens if you lose your job? Let's say automaker leaving town for more profits, leaving behind thousands without jobs? (Mind you they were already/still profitable at this point.) See, life is grey not black and white... Or remember Napoleon and Hitler? The 2 little greedy bastards and what happened to them (and a few million others) because of their greediness? Now argue for greed being good... Please proceed, Governor...
A healthy dose of ambition is good, but I don't know about greed. I think of ambition as "I want more than I currently have." I think of greed as "I want as much as possible, and more than everyone else has." It is not psychologically good for people to focus on money too much. Make enough to take care of yourself and then make some more, to use for having fun and taking care of yourself when you are old. If you enjoy your work or trading, go ahead and make some more. But making money should be for the purpose of gaining freedom, joy, and other experiences. When money is an end in itself or a measuring stick used to compare oneself with others, it is subtracting from living your life. Too much focus on money should lead one to consider what insecurities or fears one is trying to hide from or cover over.
That is all well and good but who exactly determines how much someone else needs for ... having fun and taking care of yourself. One person's idea of greed is another person's idea of a healthy dose of ambition. And from opposite ends of the political spectrum "Too much is never enough". - Jerry Garcia “The problem with socialism is that you eventually run out of other people's money.” - Margaret Thatcher
You may as well ask if breathing is good. If you are a human being you are greedy, period. Whether it is "good" is a subjective judgment. You can judge it good, or you can judge it bad; either way, it'll still be part of all of us.
Yourself. Once you start to give to charity a lot because you realized there is such a thing as too much money, then you reached that point. Ask Carnegie or Bill Gates...
Must be very satisfying to have some money to give away. The donors can choose who to give it to and why. The scrooges keep it all to themselves in their meaness.
