You're forgetting that government employees (those whose jobs would be threatened by an decrease in government budget) are now one of the nation's largest voting blocs.
Combine that with the "government is charity" bullsh!t that they have sold to the general public (particularly the large low-income voting groups that pay little to no taxes), and we have one hell of an uphill battle ahead us if we want to rid ourselves of this yoke of tyranny.
Quite right, and in fact I am not sure if there is any historical backing to support it, but from what I can tell the majority - or all - of the world's Western nations are, from decade to decade, increasing taxes as a percentage of the average joe's income. As these numbers continue to increase, we're all doomed to the inevitability of a welfare state. Then, at some point, somebody will come along and say "hey this really sucks. I want some control over things again", and then the government collapses and we start again.
You can laugh at Canada's taxes - as I do - but I think the US is heading in the same direction. Unless I'm mistaken taxes are higher now than they were in 1993. Higher then than in 1983, 1973, etc.
And people don't care. If an official says "no new taxes", then he gets a slap on the back. How about a real program that aims at CUTTING taxes. If government continues to demand more money it cannot be working efficiently. In the private sector a business that can't do well either trims fat, goes bankrupt, or jacks up revenues. The gov't can't go bankrupt, and they sure don't like trimming fat, so they just jack up revenue.
