The simple answer to this question is ‘No’. In most cases money can’t buy true happiness. It seldom if ever makes a bad relationship good, nor can it improve intimacy in a relationship. People with the highest incomes often have to work long hours, and many of them quit these jobs and find work that brings them greater life satisfaction.
Once we adapt to higher incomes, it can soon lose its appeal. After a promotion and higher salary, a person often feels greater life satisfaction and happiness but in less than about three months, the higher salary can lose its impact on happiness levels.
