Besides ya'll that say it helps with taxes either are not married or don't pay attention to your taxes. Ever hear of the "marriage penalty tax"? It's not an official penalty but if both people work your income is added, most times you hit a higher income bracket and end up paying at a higher rate than if you were single. Trust me this applied to me while my wife was working but it's not as bad since she went back to school. This was one of things that President Bush was fighting in his tax reforms but I don't believe it was permantly resolved and the Democrats are trying to roll back the taxes to the way they were.
