Really you don't get it? The real economy has not gotten any better yet the markets have more than doubled since the recession began. Trillions upon trillions of dollars have pushed the GDP up a whopping couple points a year.. When the punch bowl even gets hinted at being removed the markets tank hundreds of points, this has happened several times over the last few years most recently earlier this month markets tanked huge on remarks about possible end of QE, then they took it back and markets continue to fly.
Point: The party WILL end, and it will be sooner than most think.
