I've recently got a feel for this whole "barrel of a gun" thing with taxes. This month marked the second year in a row when my increase in income is being offset by an increase in taxes (I'm not in US btw). I've never felt there's anything wrong with paying taxes: I was born in a state-funded society, and I enjoyed free education and health care. But now I do. I actually feel the hand going in my pocket and taking more then it's supposed to. And the complete lack of trust I have in the political class to responsibly use this money, hell, to just not plain steal half of it makes it all the worst.

Sorry the rant. Point I was trying to make, the devil is in the specifics. Taxes are social contract, yes, but overtaxing and then wasting the money is still stealing. Same with draft - 3-6 months of learning military skills which might be useful in case of an invasion is reasonable social contract. Drafting in order to be part of an invading army is not.
