What color is the sky in your world?
The 50% of the American people who pay no income taxes have discovered they can vote themselves largess from the public treasury, and the future is history.
Everyday we hear these same 50% complaining that our half is the one with too much power (tax-cuts for the rich, candidates bought out by the moneyed interests, etc.). By looking at the fact that neither of the two halves are anywhere near leaving the US (despite threats to the contrary every election year) I figure that virtually all Americans have more power than they have time or energy to wield.
