no one say they agree to pay taxex, and actually is the contrary, they evade taxes as much as possible
taxes are a form of a legal theft
I think everyone agrees to pay taxes when they pay voluntarily pay them. If people want to live and work in certain countries they have to play by the rules and laws set there, but people are free to move to a country where you don't have to pay taxes but usually there's a good reason why they don't.
It is not wise never to question the rules and laws and seek justification for them. We pay taxes from our income, then from everything we buy part goes to taxes too, that what is left we pay taxes on our savings or assets for having not spent the value of it.
But where does the money go to? Does it reflect in my surroundings, is there enough to justify the amount collected to benefit my social wellbeing? Education, expensive royal families, infrastructure..
