For quite some time, I read Krugman expecting insights.  I have not found them.  Were he concerned about the ordinary Jane or Joe he would speak much less about Trump and much more about enlightened policies.  He plugs Obamacare whenever he can, yet Obamacare with its lack of cost controls will not lead to Universal medicine.  Yeah, you don't agree, but the rich in the medical industry just get richer and richer at he price of lower levels of care for all.  He does not advocate for high marginal rates on ordinary income such as is earned by millionaire doctors, lawyers, CEO's and the rest of the privileged class.  Capital gains should be low to stimulate new business activity (as active investors only), but W2 income should be taxed at 95% above 300-500K.  Even Obama in early years wanted to raise high income marginal rates.  I see no support for any productive actions on Krugman's part.  He does apparently support massively deficit spending.  Untested, no proof it works.
