The vast majority of America does not work for the government. Just bringing this up would highlight a division we need to highlight sooner rather than later-- one America which pays the taxes and one America which consumes them.
The America which consumes the taxes should not be living better than the America which pays the taxes. What will happen to the former when the later decides they've had enough?
The vast majority of America doesnt vote either, while government workers vote in larger numbers than the population at large.
I agree with everything you say but political reality is what it is. Ask any elected politician they will readily admit they are not about to buck the Government employees union.
Just think about it, if you threaten government workers jobs they are going to turn out at the polls in record numbers. Do you think the supporters of this plan will turn out in similar numbers? I doubt that congressmen are going to bet their jobs on it.
Something like the French Revolution.
