There is no truce & never has been as far as the purveyors of Libertopian claptrap are concerned. They've been winning at top down class warfare for nearly 40 years.
Well, it's all a matter of degree, though. One could say there's been a low-intensity (and rather one-sided) class war underway since the advent of neo-liberalism, but then I think, that's far too parochial a picture, it's been going on forever, from the enclosures to the Peterloo massacre to the extremely violent labor disputes of US history, and on to today. And that's not even considering the global picture and colonialism or slavery or the genocide of the American Indians.
Point is just that it could be far more open and violent than it currently is in the West. The current situation constitutes an uneasy period of relatively low-violence, but it could be much worse, and libertarian policies, if enacted in full, would likely do precisely that.
What political history has never been is a peaceful agreed 'consensus'. People tolerate things, if the costs of overthrowing them seem too high, is all.
