Generally agreed. Re: the markets never recovering post-Trump, he retracted that prediction shortly after making it, and admitted it was something he said in the heat of the moment, without properly thinking things through: https://krugman.blogs.nytimes.com/2016/11/11/the-long-haul
"He will, in fact, be a disaster on every front. And I think he will eventually drag the Republican Party into the abyss along with his own reputation"
