To some degree money makes you happier, but its not the money itself that does so but the workings of society as is; money is essential to live. A person with no food, shelter, ect is most likely a miserable person because they are envious and hungry and have little to nothing, however even so I've met a homeless man that lives in my area that is a happier person than a lot of people I know, or at least puts up a good front. For some people, they feel they have failed themselves and their loved ones to not be able to afford to take the best care of them, and some people who cant afford adequate healthcare suffer from sickness, ect. Beyond the basic standards of living and living up to set expectations, and having what is necessary to live. Theres also rich yet unhappy people in society.
Otherwise, Flash's topic makes really good points and I like it a lot; his argument is good too.
You dont have to be wealthy to be happy, but its comforting to know you can pay the bills and eat this week
