What does Obama personally gaining by the USA going under?

the personal gain of being a US president is only he glory. hes really not selfish as i can see, though of course anyone who general hates obama would bash him and say hes taking all of our money for himself, which is not true. they get an income of $400,000 a year, which is amazing for personal wealth, but i dont see any president that uses any situation like war to get any personal gain. its merely nonsense
