I don't agree with your last part. You are right that everybody spends most of his life working and making money, but this doesn't come from the desire to become rich. It's rather that money is necessary in our society, without it we couldn't pay rent or buy food. We all need money to survive. However there is a difference between having a good life and trying to become rich. If money would be our main goal in life then why do we take days off work, and why don't we have jobs on weekends? I believe that most of us strive for a good work life balance. Humans are not made to work 24/7, we need time with friends and family to regenerate our batteries. There are more important things in life than money.
