Paying taxes is part of a social contract.  I pay taxes and expect several things in return: security and an ever improving way of life, basically.  I had a neighbor that used to complain of paying taxes when the money went to schools and programs for school children.  I could have made the same complaint but you have to think about what that money is doing.  Putting kids through school enables adults to spend more time in the work force.  It educates children.  That's pretty much it.  I mean, that's just one example of many but you get the idea.  Also think about when new technologies such as the internet come along.  The internet is a new attack vector for pedophiles so you need law enforcement to handle it and that costs money.
