Taxation is a nationwide contribution to the government's operating budget from every person willing and capable of legally earning money.
Tax money pays for public services like police, firemen, health care, justice, garbage disposal, education, road maintenance and so on. It's a long list.
No reason why they cant be private businesses instead. Government is unneeded and free market can take care of that stuff.
This is a TERRIBLE idea.
For realsies. If I'm unhappy with my government I can fire them. There's no such possibility with a corporate alliance governing everything
