Robert Shiller, Irrational Exuberance
Populism is here to stay (both of the left kind and of the right kind), until the root cause is addressed: income inequality. It's reprehensible to have life expectancy decreased in a first world country. In fact, because this is happening perhaps we should contend with the fact that America may be, as of recently, a third world country? There's a reason why Ray Dalio, the most successful hedge fund manager of all times calls this problem "a national emergency" that may be "an existential risk to United States".
