What financial advantages do I have being unmarried?

As I've said in a previous post - when you're married in the United States, you get a huge tax advantage in addition to not having to pay singles' supplements when traveling.

It's been calculated that remaining unmarried incurs a massive financial penalty over the course of one's life (again, I'm speaking as a U.S. citizen; I can't speak for other countries' laws or provisions).

What financial advantages do I enjoy being unmarried? If I want to travel, how do I keep it from being prohibitively expensive? (married couples can afford to travel anywhere given that they don't have to pay extra per person)

Being un-married sucks in a lot of ways. Being married is far superior.

You don't get a huge tax break. Often your 'half' of a return is less than it would've been were you single.

Being married is far superior for the woman. For the man, it sucks.
