Price fixing always fails because real prices are generated by thousands of different judgments by millions of different people. No regulation could ever encompass the complexity of this process. Planning and regulation always reduce complexity just as a farmer's field is less complex than the woods it replaces. Libertarians are the most obvious. Songs and jokes chronicle our contempt for authority every day.
Libertarians are the most obscure.
Ask a hundred people on the street and perhaps five will have heard the word. Of them perhaps two will have some conception of what libertarians stand for. Since there is no plan, there is no plan to grasp, to like or dislike. No one who has, or hopes for, political power has any reason to spread the word. The media rely for much of their news on the politicians and have nothing to gain by alienating them.
