Picture an upside-down pyramid with its narrow tip at the bottom and its base on top. The only way the pyramid can stand is by spinning fast enough or by having a wide enough tip so it won't fall down. The federal version of this spinning top is the tax code; the government collects its money almost entirely from the people at the narrow tip and then gives it to the people at the wider side. So long as the pyramid spins, the system can work. If it slows down enough, it falls.
It's also what's called redistribution of income, and it is getting out of hand.
A very small number of taxpayers -- the 10% of the country that makes more than $92,400 a year -- pay 72.4% of the nation's income taxes. They're the tip of the triangle that's supporting virtually everyone and everything. Their burden keeps getting heavier.
