Since long time ago, many people have been saying this statement, which is "money doesn't bring happiness", but is that really the case?

Most people that tend to say this usually have stable income that is above minimum wage, and their main argument is "there are many millionaires that are unhappy with their lives even with all that money", but does that prove anything?

In my opinion, money is not equal happiness, but without money obtaining happiness is much harder than with stable income. People who work from 9 to 5 every day usually can't be happy, because their main focus is work, which allows no time for such things as entertainment, relationship, etc.

Feel free to discuss this subject, I'm really curious as to what the rest of the community thinks about it.
