This week Russ Roberts interviews William Bernstein on inequality. Bernstein argues that income inequality has ill effects on poorer people's health--they have a lower quality of life because they know they are on "low" end, they're more likely to stress out, etc. Thus, he says, we should engage in income redistribution.
I find the big weakness to the inequality argument is its policy recommendation. I can see how a few people making lots of money makes others upset/jealous (we hear about it all the time in politics, suggesting people like to hear about how evil wealthy people are). I can also see that such anger leads to stress and leads to unfortunate health effects. In other words, I can see how one person's increasing wealth can externalize a cost onto another.
Since transaction costs are high, let's set aside the Coase Theorem. Instead, who's the least cost avoider? (Remove the wealth or remove the sadness and either way we have no problem so what's cheaper to remove?) If we ask the rich to make less money, we would lose those the benefits that the person would contribute to society. If we ask the poor to take a breath and let it slide, we likely lose much less for what we get. In other words the conclusion should not be redistribution but people dealing with it on their own terms. Bernstein should be telling people to pick up yoga, not pick pockets.
