I think the happiness lies in knowledge because when we have enough of knowledge we can easily get how much ever wealth we want. the happiness would every time lie in the side of the knowledge only but not the by the side of the wealth.   
"Happiness lies in the joy of achievement and the thrill of creative effort." Franklin Roosevelt.
According to me, happiness lies in knowledge because knowledge is the key to success and on the other hand wealth is something that can be stolen but knowledge can not be !

“The Seven Social Sins are:
Wealth without work.
Pleasure without conscience.
Knowledge without character.
Commerce without morality.
Science without humanity.
Worship without sacrifice.
Politics without principle.
