People, I want to point out that I dont like Piketty's ideas (no shit) but I wont ding the man for finally bringing into English what he has been saying in French for years. I respect that. As much as I dislike his views, I respect the move of pushing big ideas.
What I will point out is what no one wants to listen to that I have been saying (in French, English and German) for years. Piketty often arrives at "big ideas" with really sloppy work. I have four big papers on inequality measurements pre-1960 that deal meticulously with aspects of the data works: assumptions, data quality, theoretical underpinnings, statistical estimation techniques. They span a good decade of work.
The big takeaway is that none of what was initially advanced "factually" in Capital in the 21st Century or Capital and Ideology to justify the big ideas hold.
Inequality in America pre-1943 was massively lower; the trend was different; the golden age of equality was not as golden nor was it tied to tax policy that much; inequality was falling from 1870 to 1943 (my forthcoming book), the rise post-1980 in inequality is much smaller than depicted, the welfare moderated massively post-tax inequality rise since 1960, social security acted as a massive wealth equalizer. All of these facts which are based on higher precision (but not perfect) statements undermine all the "big ideas" he moved forward.
Moreover, all the errors in fact fit his preferred ideas. I have pointed out that some of my findings irked me as a classical liberal (notably with respect to the welfare state and social security). But the facts are stubborn buddies to hang out with. And what is more annoying is that none of corners cut were necessary. As I pointed out in a first review of my peer-reviewed papers which I wrote for City Journal: none of the findings I make preclude positively the call for greater income and wealth inequality. The first image is what I wrote back then on the matter. I wrote a similar thing in German for
@faznet (I will post the translation in reply). That is even more frustrating than the errors themselves because they seem to have brought into existence as errors for the purposes of easing the case he wants to make -- a case which is not automatically invalidated by the data. Normative positions can be held without the need for positive prior outcomes.
Ultimately, the list of errors has been ignored and people talk about the "big ideas" without reference to the foundations used to bring them about. That is what I wish people would think about. That the factual foundations are shaky even if I do not think they are necessary to make the "big ideas".
Things can be discussed separately!
Everyone is talking about how bad the ideas in this Piketty proposal are, and it's true: They're very bad.
But what's also notable is how *out of date* they feel. A one-world government to fight climate change? Seriously? Even Greta Thunberg has moved on to Palestine activism.
