Bill Gates in his blog:
I’m glad I did. I encourage you to read it too, or at least a good summary, like this one from The Economist. Piketty was nice enough to talk with me about his work on a Skype call last month. As I told him, I agree with his most important conclusions, and I hope his work will draw more smart people into the study of wealth and income inequality—because the more we understand about the causes and cures, the better. I also said I have concerns about some elements of his analysis, which I’ll share below.
I very much agree with Piketty that:
- High levels of inequality are a problem—messing up economic incentives, tilting democracies in favor of powerful interests, and undercutting the ideal that all people are created equal.
- Capitalism does not self-correct toward greater equality—that is, excess wealth concentration can have a snowball effect if left unchecked.
- Governments can play a constructive role in offsetting the snowballing tendencies if and when they choose to do so.
To be clear, when I say that high levels of inequality are a problem, I don’t want to imply that the world is getting worse. In fact, thanks to the rise of the middle class in countries like China, Mexico, Colombia, Brazil, and Thailand, the world as a whole is actually becoming more egalitarian, and that positive global trend is likely to continue.
But extreme inequality should not be ignored—or worse, celebrated as a sign that we have a high-performing economy and healthy society. Yes, some level of inequality is built in to capitalism.
