Jeffrey Sachs was on the Daily Show last night to promote his new book, Common Wealth, in what turns out to be the least entertaining Daily Show interview ever. It’s repetitive and vague; Sachs says we all must work together to fix the world’s problems, Stewart asks which problems we must solve, Sachs then names about 5 problems and says we must work together to fix them, etc. Stewart concludes the interview with an awkward, nonsensical joke about Poland and then it’s all over. Like it never even happened.
