For me it is undoubtedly that money and happiness were interrelated and mutually supporting each other. People's opinion and insights about money may differ from each other but we are all working out for the same goal to live everyday and to earn money. Happiness is immeasurable but money could give you the privilage to buy things that you wanted to buy, buy foods because today everything comes with a price. Also it is much happier to live a life with a financial worry less than with heavy problem in terms of money matters right
as many people say that money can't buy happiness and that's true too,
but we don't have to lie to ourselves that without money we will certainly starve to death so both money and happiness complement each other
