Paul Krugman wrote an op-ed in the NY Times about it today. He too says what Piketty says is self-evident, although the right-wing economists and politicians in the States have called Piketty a Marxist because they have no arguments other than insults.
have called Piketty a Marxist because they have no arguments other than insults.
The assumption that dismissing someone as a Marxist is ipso facto an insult is itself an indication of their limitations. He was appallingly wrong or naive about plenty of things, but a shrewd analyst of many others. The problem with too many economists has been blind faith in the policy prescriptions they derive from their analysis, right back to the "political economy" orthodoxies whose deficiencies Marx was pointing out.
Ever since "capitalism" claims to have won the Cold War, too many people seem to be unable to question its validity. I have to admit that it is comforting to live in a country that still has enough communists and other anti capitalists to keep the debate alive. While I am not a defender of communism, I believe it is good to have other belief systems to challenge the ones that are dominating us (and which are generally presented as the "only" option).
"Communism", of course, can mean anything. At one point I worked in the communications department (service d'information) of a leading Québec trade union confederation. And met trade unionists persecuted by their respected governments. Nothing much more similar than Chilean "communists" and Polish "anti-communists".
As for their persecutors, they even sported similar dark glasses...
