Chart of the Week: How two decades of globalization have changed the world

Sometimes a graphic inspires us not by its creative animations or mesmerizing interactive elements, but by how much it can explain with how little. That’s why we like this chart from Branko Milanovic, lead economist at the World Bank’s research department (as annotated by James Plunkett, policy director at U.K. think tank Resolution Foundation). Milanovic likes to call it, “How the world changed between the fall of the Berlin wall and the fall of Wall Street.”

The vertical axis measures real income growth (measured in constant dollars on a purchasing power parity basis) between 1988 and 2008. The horizontal axis shows not time but income levels, from lowest to highest. For example, the second dot on the chart marks the 10th percentile of income, meaning people who outearned just 10% of the world’s population; that group saw its real income rise more than 40% over that 20-year period.

The top 1% clearly did well during the period under study, but Milanovic notes that the biggest gains occurred further down the income ladder. “It is there…that we find some 200 million Chinese, 90 million Indians, and about 30 million people each from Indonesia, Brazil and Egypt,” he writes. “These two groups — the global top 1% and the middle classes of the emerging market economies — are indeed the main winners of globalization.”

Even among the bottom third of the global income distribution, real incomes have risen significantly; overall, Milanovic writes, “[i]t was probably the profoundest global reshuffle of people’s economic positions since the Industrial Revolution.”

The “losers” are the bottom 5% (mostly people in Africa, Milanovic says), and people clustered around the 80th percentile. Most of that latter group live in developed countries — some in post-Communist countries that haven’t adapted well to globalization, but also the lower middle classes of advanced economies such as the U.S. and Germany. Does that prove that Asian gains have come at the expense of U.S. workers? Milanovic is very cautious on that point, saying that while “[g]lobal income data do not allow us to establish or reject the causality…they are quite suggestive that the two phenomena may not be unrelated.”

    Its not surprising that the rich are getting richer and fewer, capitalism, although pushes ahead with consumerism it leaves behind a generation or two quite incapable of fending for themselves and the ensuing whiplash of revolution will herald in robotic technology just being created. in Australia plans are afoot to keep up with the international Jones’s while leaving behind the generation which built its wealth now being politically wasted.

    On a brighter note, but only for the ruling elite, robot armies are on the way to both serve the elite and to kill off the plebes no longer needed.

    Welcome to your future, not mine; I’m nearly 72 and won’t be around to see the slaughter.

    This graphic suggests that we should strive to get back to the Great Depression when real incomes were rising, and that the laudable growth in incomes in China in the early 1950s had nothing to do with the now well-documented intentional starving of 20 millions of people to death there during that period (actually that suggests a proven way to raise average income–murder a larger percentage of a population). This is a very misleading presentation of data and one that suggests that real income growth isn’t very important out of context.

    The crucial missing element in this upbeat-looking graph is population in each income strata; how many people are in the 5% and under income level? How many in the 80% income level?

    Thanks to Mr. DeSilver for giving us a clue: “the biggest gains” include about 380 million people, just 6% of a world population of 7 billion. Six percent, plus a tiny number of top 1%.

    It could well be that 80-90% of the world population is in the <5% and 80-85% who have gained nothing or been losers. Add the immense loss during the years following 2008, and you have a world disaster of immense proportions under the various current socialistic systems.

    Store food, clothing and, where possible, fuel and some gold or silver coins. That's how it looks from the rock I'm sitting on.
