Earlier quoted context omitted.
Taxation is not theft, it is lawful. The developed world is founded on taxes.
How much is considered lawful? 30%? 50%? 90%? It would be lawful if I agreed to all of it. I do agree we need taxes, but in many cases, it's excessive and against my will (you can go to jail if you don't pay it). The other problem is that there is no accountability.
I'm assuming you live in China though, since you said there is no accountability, and you can't vote out public officials whose tax policies you don't like.
