Thomas Piketty has come a great distance. He first captured public consideration in 2014 together with his wildly bold, 704-page updating of Marx’s Das Kapital, entitled Capital within the Twenty-First Century. A part of its attraction – it turned each a world bestseller and an educational sensation – was the simplicity of its fundamental thesis. Though filled with historical past and statistics, its basic proposition, that if the return on capital exceeds the expansion price of the economic system, wealth will grow to be more and more concentrated, may very well be lowered to at least one easy equation: r>g.
Piketty’s newest e-book is nearly precisely the other. Not solely is it a lot shorter, based mostly on a lecture given to the Société d’Ethnologie in his native France, its key message is: “It’s much more sophisticated than that.” Like Capital, it discusses the evolution of earnings and wealth inequality over historical past. But it surely emphasises historic contingency and, most of all, the position of politics and of collective mobilisation.
Piketty rejects the thesis – implicit in the best way economics is commonly taught in our universities, and express in the best way some economists and lots of conservative politicians and commentators focus on coverage points – that very massive inequalities are the inevitable final result of a well-functioning market economic system. That concept – that nice disparities are in some way “pure”, as a result of skill or entrepreneurialism is erratically distributed throughout people (or international locations, or ethnic teams) – can also be used to argue that efforts to cut back inequality will both be ineffective or scale back progress and prosperity, or each.
Piketty factors to acquainted counterexamples: Sweden, the place social democratic insurance policies led to a rustic that had been extremely unequal as lately because the interwar interval turning into one of the vital equal within the world, whereas on the identical time turning into one of many richest. And the US, the place very massive tax cuts in the course of the Reagan period led to spiralling inequality, however with none commensurate enchancment in financial efficiency. In each instances, the important thing drivers have been political and traditionally contingent.
So if inequality is neither inevitable nor useful, what ought to we do about it? In Capital, Piketty positioned a substantial amount of emphasis on one potential coverage device: a world wealth tax – easy sufficient in principle if extremely complicated and politically problematic in observe. He hasn’t backed off from his view that taxation – of earnings, capital and inheritance – ought to be extra progressive, right here extending that concept to carbon discount mechanisms. Many economists would agree, at the very least in precept, and much more would endorse his view that over the medium to long-term one of the best ways to cut back inequality is to speculate way more cash, extra equitably, in training.
However Piketty goes additional, arguing that what’s required is a broader rejection of market mechanisms: creating the welfare state entails greater than redistributing cash equally; “above all it requires taking sure items and companies out of the market”. Whereas that is uncontroversial for training and healthcare, Piketty doesn’t cease there: “In the long term this might probably signify the close to totality of a rustic’s financial exercise.” Simply the collective possession of the technique of manufacturing, then. How would this work? Properly, he does give an instance: the Guardian’s Scott Belief.
And there the chapter ends, unconvincingly. For these of us who share Piketty’s normal outlook and far of his evaluation, this shall be greater than a bit irritating. If it’s collective political mobilisation that drives coverage change, the place does that come from and the way does it relate to the present state of the worldwide economic system? Maybe probably the most evident omission is any point out of the tech sector, which is behind a lot of the latest focus of each wealth and political energy within the US, and threatens to play the identical position elsewhere. Piketty ends with a problem to social science researchers of all disciplines to interact with the financial and political points arising from the unequal distribution of wealth and energy. Certainly, I might argue that this is the place they need to begin.
