I'd say it's a combination of A: a long period of relative stability and B: in the west, everyone is freakishly wealthy by historical standards and has a lot to lose, thus, you lack a base of desperate people with nothing to lose. (Chatter about "wealth inequality" in the West can sometimes cover over the fact that by historical standards, we have basically cured poverty as much as we can, modulo some fiddling around the edges of incarceration vs. institutionalization vs. homelessness at the fringes. Doesn't mean it's not bad or not a problem, but it does pay to contextualize it historically every so often, to stay grounded.)

On the other hand, it does mean that if there any sort of instability, people will have to rediscover from scratch how to deal with it, a process that sounds relatively painful to me. Here's hoping we never really have to find out.
