I hardly here "populism" in the news and I just googled it and see that pretty much the only one talking about it is Pence; kudos to him. So apart from Pence I'd argue nobody talks about populism and the only people tossing out "free market capitalism" are doing so in the negative. I'll argue that more free market capitalism is what we need with the caveat that there are many "free market capitalists" that are not free market capitalists.
But I'll agree tossing out buzzwords is not fixing a problem, it's attempt at demonization mostly IMHO.
