Excellent point Beskar, you are however overlooking the fact that the USA per definition never fail and when they do it's the fault of the evil commie socialists who want to turn the USA into another Europe(and that's something you really got to be afraid of!)...

I don't think limiting the voters on the basis of taxation and government help is a very good idea. I know a guy who was unemployed but didn't lose his faith in capitalism. And then you could find hundreds of other reasons to exclude people from voting because they wouldn't vote for the party you prefer.
