might be because america has the highest proportion of non white parasitic minorities in the developed world. people don't like being taxed to support black welfare queens with 6 kids by different men.
Nobody likes being taxed, period.
Part of the problem with US Libertarian idealists is that they've got this elaborate (yet flaky) house-of-cards built up about how politics and the economy and everything "ought" to be, but at the same time they've got these huge blind spots such as opportunity cost.
Thanks to your tax dollars, those welfare queens and their 6 kids aren't hungry enough to murder you in the street for a small amount of pocket money, or just for the protein. Yeah, yeah... you'd much rather have the "freedom" to spend those tax dollars on a private security company to save your ass from being attacked in the streets (and endless toll roads and related shit). And of course that would be
far more efficient than public/state services, because free-market competition and stuff, just like Bitcoin miners -- LOL. .
