Earlier this month, I offended a number of readers with a column suggesting that if you want to see rapacious income inequality, you no longer need to visit a banana republic. You can just look around.

My point was that the wealthiest plutocrats now actually control a greater share of the pie in the United States than in historically unstable countries like Nicaragua, Venezuela and Guyana. But readers protested that this was glib and unfair, and after reviewing the evidence I regretfully confess that they have a point.

That’s right: I may have wronged the banana republics.

You see, some Latin Americans were indignant at what they saw as an invidious and hurtful comparison. The truth is that Latin America has matured and become more equal in recent decades, even as the distribution in the United States has become steadily more unequal.

The best data series I could find is for Argentina. In the 1940s, the top 1 percent there controlled more than 20 percent of incomes. That was roughly double the share at that time in the United States.
