Money can buy:
-Food for starving chlildren
-Medical supplies for the sick
-Tickets to see your idol live in concert
-A roof to sleep under
-An expresso for a dog tired college student
-Internet access to skype your family that lives 2,000 miles away
-Chocolate when mentstruating
Yeah, I'd say money can buy a lot of happiness. Now, most of these things are fleeting. I'f you're talking about lasting happiness, like eternal love, then nope. Money's no good for that.
