I don’t think it’s a bad trait I think it can be used positively! If the world was more greedy with their money they may have saved some for a rainy day but instead kept spending and drove unproductive greed
I think that we like to conflate wealth with greed but some actually worked for their wealth and then we look at those in need some actually chose that because of the bad decision they make not all poor people are a victim of circumstances but a victim of themselves!
