It's a complicated question. Money can be used as a tool, it can be used as a drug, it can be used as a weapon. To make a blanket statement like "all rich people are evil" is pretty invalid, just like saying "all poor people are lazy" - neither are true, they run the entire spectrum of humanity.

Does it "buy happiness" -- well, I live in an affluent town, and, while people do try to buy happiness with it, the fundamental things that affect life are the things that can't be bought - health, relationships, family, friendships, community. Health is a good example - I can't "buy back" my recent mental health history, no matter how much I wanted to. I suppose I could try to bribe people in key places. Blue Cross and the hospital records department, to make the records disappear -- good luck in the real world finding those people. I have been throwing money at this problem to try to "fix it" -- it doesn't work - not bribes, all kinds of therapy, medical treatments, etc. It's still here.

Do people here have problems - of course. Money just makes it more easy to hide them, gloss over them, and people have a level of decorum/behavior that makes it less overt most of the time. But, the problems are still there.
