I must disagree with those that suggest the Libertarian party exists in large part due to Ayn Rand. I have never read Ayn Rand, no one I’ve known IRL who knows something about Ayn Rand has thought much of the books, philosophy, etc. Yet, I have strong libertarian tendencies. I think one reason the US has stronger libertarian tendencies than Europe is our society’s assumption about what government is for.
Let me try some parables. Suppose my neighbor wanted to rent a room, and a gay couple expressed interest, but the neighbor did not want a gay couple living in his house.
Democrats: This is discrimination. Pass a law making my neighbor’s act illegal. I.e., use the government to solve the problem.
Religious Conservative Republicans: Gay acts are immoral. Pass a law making homosexual acts illegal. I.e., use the government to solve a problem.
Libertarians and other Republicans: The free market can solve this “problem”. Someone else will rent to the couple, because there is money to be made. I.e., it is not the governement’s role to solve the problem.
A major U.S. corporation is going bankrupt. Incompetence is to blame, but maybe also some shady dealings.
Democrats: The workers have been shafted. Pass legislation preventing the acts that led to the downfall.
Republicans: The shareholders have been shafted, bail out the company.
Libertarians: Well, that’s too damn bad. I guess some other company will be selling whatever they sold now.
To my understanding, libertarians believe the government exists to ensure everyone’s rights are protected in a Lockeian fashion. A government that can take your property violates the very reason for having a government. Democrats believe the government exists to solve problems, while Republicans believe the government exists to maintain a system that “works”. On some topics Republicans are nearly Libertarian (economy), while on other topics Democrats are (weed), but all three are motivated differently. (In my mind, that is why Democrats were presidents for most of the 20th century US wars. The military is a branch of the government.)
Debating specific Libertarian policies does not answer why Europeans do not seem to have many libertarians. Is it because most European governments came into existence in their society’s attempts to solve internal problems - monarchial government, etc, and the US government came into existence to solve an external problem? Certainly Locke and his brethern had much to do with the history of the English government. Did libertarian philosophy wither with the advent of democracy? Or is it so deeply enmeshed in the society that there is no point for such a party?
