Your statement might have been true a few decades back. But now, most of the tax revenue is being spent on the defense budget, and for giving salaries to the governmental staff.
Officials receive a large salary and still use money from paying taxes for their own purposes. I do not like such a payment of taxes.
In order to start taxation change, you have to realize that governments do not tax their people. A government is simply paperwork. That is why a government is referred to as a state. The state is simply a state of mind that has been written on paper. Paper can't do anything. It can't jump up and down. It can't drive a car. It is always people doing things.
Taxation is merely people forcing other people to give their property over to them.
Once you get this through your head, that taxation is people forcing other people to hand over their property, only then will you have a clear enough view of things to start to figure out how to change laws so that there is no taxation.
