"Tinkerbell Politics: you can if you believe!"
Politicians and their supporters believe there is a magical power behind government, and when politicians issue a mandate, reality morphs to conform. Is there a climate problem? We just need new laws! What do you mean, this imposes new costs upon people who can't afford the burden? Is there a drug problem? We just need to prohibit drugs, and no one will be able to get them! What do you mean, "black markets?" Where did this gang violence come from?
Governments produce nothing demanded by the market without first taking wealth out of the market through taxation on market actions and inflation of the money supply. Governments operate as a monopoly with all the attendant waste and abuse that goes with that status. Since governments do not operate by market action, they are not constrained by the discipline of consent, profit, and loss, so they have no rational way to make any economic calculations. Belief that such a system can really solve any societal problems is a flight of fancy beyond anything in Peter Pan.
Progress is messy, but only a grassroots effort built on respect for consent and individual liberty will bring us forward. Politicians offer only counterfeits. Never be seduced by their promises to the contrary. Belief does not override reality.
