All Libertarians are morons; there are just different types of stupid.
America is probably one of the only countries in the world where Libertarianism has any kind of sway at all, although I understand that for some reason, it is relatively popular in Costa Rica for some reason, possibly because the country is heavily White. Whites are the only race on Earth who will heavily go in for Libertarianism, because Whites are much more selfish and individualistic than any other race. European, Australian, Canadian, and New Zealander Whites are not prone to selfishness of individualism.
Selfish and individualistic politics is popular among White elites in Latin America, but only in places where Whites are a minority.
In Argentina, Chile and Uruguay, where Whites or near-Whites are more or less a majority, selfish and individualistic politics is far less popular, since your average White person there is just an ordinary working class person, not a member of an elite group.
Nevertheless, the Cone nations have been ruled by a particularly vicious White elite for a long time. This elite has spent much of the last 40 years slaughtering the working class Whites of the Cone countries in order to maintain their outrageous and feudal-style wealth. As a consequence, White politics in the Cone is polarized into Hard Left and Hard Right, in a way similar to some Mediterranean countries like Italy, Portugal and Spain.
Small government is popular with White elites, as this philosophy in general is only popular with elites around the world. The German Social Democrats used to have a saying, “Only the rich can afford a poor state.” Of course this is true, and this is why the rich the world over, especially in the 3rd World, tend to favor a minimal state. Hatred of taxation is also typical of elites the world over, particularly in the 3rd World.
In general, ordinary people the world over do not favor small government or hate taxation. In that sense, Americans, particularly White Americans, are very strange. The views of White Americasns are more typical of world elites than the ordinary working class people of the world. It’s as if your ordinary working class White person identifies more with his class enemies, the rich, than with his own class. Working class Whites also see themselves as elites, which is odd, since they are not elites, and in fact they are extremely oppressed by their own elites.
This strange philosophy probably has its roots in the Frontier Ethic, the break from colonialism, and the radical individualism that has long characterized White American culture.
As America becomes increasingly non-White, this view will decline. Asians are not radical individualists, and Asian nations are not characterized by small government and low taxation. Hispanics and Blacks are collectivist peoples who also have no interest in small government and low taxation. Black nations are like Asian nations in that there is no interest in Libertarian-style governance.
These trends show no sign of changing in the future. Even as Asians, Hispanics and Blacks make good money and move up in the world, they retain their collectivist roots.
The future does not look good for Libertarian types in the US in the long term, though they may make some gains in the short term.
The future looks bleak for Libertarianism in the world at large, as most nations have no interest in small government or low taxation.
Seen more properly, the vast majority of the world’s people, and the overwhelming majority of the working class, are collectivist people.
