I believe that the floor is going to fall out from under the US dollar. They are borrowing way too much money from the Fed to ever sustain itself. Obama has borrowed more money in his 4 years the every president combined starting from George Washington.
You should look for a guy named "Peter Schiff" on youtube. Hes an economist and investor and predicted the recession and everything else. He believes that the US will collapse. House prices will fall even more and the dollar will literally be worthless. Like where a loaf of bread may cost you $100 or $1000. Hes buying gold & Silver in Bullion and suggests everyone do the same.
