Socialists and statists have it so easy.
•Create a group identity or cultural history that spans as many people as possible.
•Create an out group who are the enemies.
•Make up a bunch of statistics by using useful idiots in the field of empirical economics, logical positivism and historicism.
•Find out shared problems that your target group thinks is important.
•Blame it on the out group as the cause for all their problems.
•Use rhetoric that appeals to emotions. (Anger and resentment are the most effective.)
•Set up media, education and entertainment pipelines for propaganda. News channels, movie and tv production houses, universities, school syllabus, online brands, podcasts, etc.
That's it. They now have an army of people who are morally and ethically bankrupt and will be okay with almost any political action as long as they think it benefits them somehow.
Libertarians on the other hand fight among themselves endlessly and make sure that their ideas are refined, irrefutable and logically consistent. They lose alliances because of in-fighting, slowing down the movement further.
They never stoop down to the level of populists even though the state is the best outgroup to be angry at and resentful of. And non-aggressing people are the most peaceful in-group to identify with.
They need to articulate and make people understand the logic of human action and the ethics of private property and self-ownership. They need to justify why victimless crimes cannot be legally prosecuted. They need to educate people about the seen and unseen effects of economic planning and intervention. They need people to be reasonable or get them to discover their reasoning faculty.
They are on the right side of history, but yet their ideas don't become as mainstream as they want it to be.
They have it tough.
