This world has been ruled with only two things MONEY and POWER.If you have money you can acquire power and vice versa.
Happiness is something which is not linked to money at all.With money or without it,happiness comes from within.
This whole discussion is wrong because poor people who think about money all the time are unhappy and same is true for people with money.Money is road to happiness not the happiness itself.
It should also be noted that having money is not a sin or curse and not having money is also not a blessing.
