This is a childish question. Something like asking a child if they like their father or mother more.

Obviously both wealth and happiness are important. You can also add health to the mix.

Unless you are the buddha himself you will need some sort of wealth backing up for your worldly needs such as food, shelter and clothes. and why wouldn't anyone want happiness? ask yourself if there could be anyone who would prefer to be unhappy.

A good question to ask would be " why do people ask dumb question?" another one "why do people answer dumb questions?"
