Paul Krugman (Branko Milanovic) about income distribution and income progress

Burgess COMMENTARY

Recent History in One Chart

A number of people have been putting up candidates for chart of the year. For me, the big chart of 2014 wasn’t actually from 2014 — it was from earlier work (pdf) by Branko Milanovic, which I somehow didn’t see until a few months ago. It shows income growth since 1988 by percentiles of the world income distribution (as opposed to national distributions):

Photo What you see is the surge by the global elite (the top 0.1, 0.01, etc. would be doing even better than his top 1), plus the dramatic rise of many but not all people in emerging markets. In between is what Branko suggests corresponds to the US lower-middle class, but what I’d say corresponds to advanced-country working classes in general, at least if you add post-2008 data with the effects of austerity. I’d call it the valley of despond, and I think it’s going to be a crucial factor in developments over the next few years. More eventually.

Twin Peaks Planet

In 2014, soaring inequality in advanced nations finally received the attention it deserved, as Thomas Piketty’s “Capital in the Twenty-First Century” became a surprise (and deserving) best seller. The usual suspects are still in well-paid denial, but, to everyone else, it is now obvious that income and wealth are more concentrated at the very top than they have been since the Gilded Age — and the trend shows no sign of letting up.

But that’s a story about developments within nations, and, therefore, incomplete. You really want to supplement Piketty-style analysis with a global view, and when you do, I’d argue, you get a better sense of the good, the bad and the potentially very ugly of the world we live in.

So let me suggest that you look at a remarkable chart of income gains around the world produced by Branko Milanovic of the City University of New York Graduate Center (which I will be joining this summer). What Mr. Milanovic shows is that income growth since the fall of the Berlin Wall has been a “twin peaks” story. Incomes have, of course, soared at the top, as the world’s elite becomes ever richer. But there have also been huge gains for what we might call the global middle — largely consisting of the rising middle classes of China and India.

And let’s be clear: Income growth in emerging nations has produced huge gains in human welfare, lifting hundreds of millions of people out of desperate poverty and giving them a chance for a better life.

Now for the bad news: Between these twin peaks — the ever-richer global elite and the rising Chinese middle class — lies what we might call the valley of despond: Incomes have grown slowly, if at all, for people around the 20th percentile of the world income distribution. Who are these people? Basically, the advanced-country working classes. And although Mr. Milanovic’s data only go up through 2008, we can be sure that this group has done even worse since then, wracked by the effects of high unemployment, stagnating wages, and austerity policies.

Furthermore, the travails of workers in rich countries are, in important ways, the flip side of the gains above and below them. Competition from emerging-economy exports has surely been a factor depressing wages in wealthier nations, although probably not the dominant force. More important, soaring incomes at the top were achieved, in large part, by squeezing those below: by cutting wages, slashing benefits, crushing unions, and diverting a rising share of national resources to financial wheeling and dealing.

Perhaps more important still, the wealthy exert a vastly disproportionate effect on policy. And elite priorities — obsessive concern with budget deficits, with the supposed need to slash social programs — have done a lot to deepen the valley of despond.

So who speaks for those left behind in this twin-peaked world? You might have expected conventional parties of the left to take a populist stance on behalf of their domestic working classes. But mostly what you get instead — from leaders ranging from François Hollande of France to Ed Milliband of Britain to, yes, President Obama — is awkward mumbling. (Mr. Obama has, in fact, done a lot to help working Americans, but he’s remarkably bad at making his own case.)

The problem with these conventional leaders, I’d argue, is that they’re afraid to challenge elite priorities, in particular the obsession with budget deficits, for fear of being considered irresponsible. And that leaves the field open for unconventional leaders — some of them seriously scary — who are willing to address the anger and despair of ordinary citizens.
