“A democracy cannot exist as a permanent form of government. It can only exist until the voters discover that they can vote themselves largesse from the public treasury. From that moment on, the majority always votes for the candidates promising the most benefits from the public treasury with the result that a democracy always collapses over loose fiscal policy, always followed by a dictatorship. The average age of the world's greatest civilizations has been 200 years.”
― Alexis de Tocqueville
Why is it that single women and minorities are the most loyal Democratic voters? They know which party will offer them the most goodies (at someone else's expense).
I hope that we as a nation are not doomed, demographics do point in that direction though: The underclass is growing and the productive classes are not.
Added: I was discussing these issues with my 15 year old daughter and she pointed out (correctly) that it is rational for people to vote in their own interest. We fairly explain the votes of the dependent class, but why to elites vote to the left so often? They make a lot of money and would be hit hard by higher taxes, it is certainly not in their interest to vote the way they do. Maybe it is a mirror image of What's the Matter with Kansas?
