Fraud:
Heres an exageration to drive the point.
Imagine you go to your bank account right now, take 2000$ out, and pay 2000$ in taxes for the Alphabet. You learn, that the government's campaign was financed by a law firm ABC INC, that the misiter was working for ABC INC, and a law was passed stating that ABC INC is now being given the rights to the Alphabet, and you collectively need to pay millions upon millions, every year, if you want to use the alphabet of the english language. You need to use the alphabet, well then you have to pay for it, and if you dont have the money, you will owe it at interest. Thats a fraud imo.
