Krugman doesn't just talk about money he talks about how money and the policies surrounding it affect the average person. I like the way doesn't mind "calling out" those behind failed, silly and biased economic policies. I sometimes wonder why he doesn't work for the government...I think the answer is because his thinking is way ahead of it.
Great to read alongside his columns. His printed articles are sometimes too concise or lacking in the empirical data/sources I would like to see. This fills in those gaps.
