Personally, I don't think it's a case of us "loving" money, it would be like saying people love oxygen... Most people don't love it, they need it and they like having it to spend to improve their quality of life. Admittedly, it is not the solution to ALL problems, but I've not yet found many problems that won't go away rather quickly if you hit them over the head with enough money!
Look at the Haiti situation, if people with money didn't give it in aid, there would be a horrible situation there right now. I don't know of anybody that actually LOVES money, but I do know lots of people that would love more money!
Good question, btw
