I think it depend on what's happiness from. Some time, we know that money can by happiness from feeling of person.
Because it just only feel, it isn't the thing that easy to buy. But if happiness of person from something like you want Iphone 5 ,
but you haven't enough money to buy it .It make you so sad and no happy. So if you have enough money to buy it, you will buy your happiness too.
