Because there's no profit motive, government is very wasteful.
...
How do you introduce the profit motive into the design of a 25 year immigration policy?
How do you introduce the profit motive into a national transportation policy?
How do you introduce the profit motive into the design of voting districts?
How do you introduce the profit motive into municipal zoning decisions?
How do you introduce the profit motive into abortion or capital punishment or firearms ownership issues?
Please don't answer these rhetorical questions, they are presented to you only the for purpose of self-reflection. Surely even you should be able to understand that the function of government is not the same as the function of private companies. This is not at all a difficult concept. or even a controversial one.
Let me give you a simple example. Buying and selling black people was very profitable, but government stopped it anyway. Buying and installing asbestos made a lot of people money but it was stopped. Building very polluting cars was once normal. Government forced us to stop that, automobile manufacturers continued to make profits AND we ended up with better cars.
Please, please, I'm begging you, stop saying stupid shit. Educate yourself, it's not difficult.
