Moneys are tool. They can't buy you happiness but they can buy you things that bring you happiness. With money you don't have to sell your time doing some job that you hate, so you can buy a dinner, have a home, have electricity, running water, have free time for some hobby or to meet new people. When people say money can't buy you happiness they thing of the miserable people who have a lot of money but they are not happy. For me they are "sick", I can't understand people who have, let's say 10 mln, but are actually slaving 12-14 hours a day to make another 10. At the end, nobody will take his money with himself when he dies, so their function is only to make your life easier.
