MotherJones Attempts Mythbusting… & Fails
Call the it the little hypothesis which thinks is can, or at least, the little hypothesis which because people thinks it should, must be.
From Mother Jones discussing income inequality between the rich and the poor, decides that those, in this case Matt Yglesias noting that when America sees economic growth, all income groups fair better, are completely wrong [emphasis added] (here):
This is a surprisingly hardy myth, and I’d like to help it die the grisly death it deserves and I’d like to help it die the grisly death it deserves. Here’s a chart showing real per capita GDP growth in the United States over the past century. I’ve helpfully added a straight red line for the period from 1950 to the present day:

US Per Capita Increase in GDP
The past 30 years simply haven’t been a low-growth period. In fact, economic growth has been about the same as it was in the 30 years before that. Our problem isn’t growth, our problem is that the returns to growth have increasingly been skewed in favor of the very rich.
& that’s it. The article continues about how modern liberalism needs to fix this, yet they offer no proof that it’s actually happening other than a single statement. In fact, the only thing in the article which might be used as evidence for something, the graph is about GDP trends, per capita.
So if you, like me, have been staying up late nights wondering just how much fame you might get in by answering the unsolvable question: how has the US economy fared over the past 100 years, I must say I’m sorry. We lost. MotherJones has beat us to it. So if asked in the future, you can now safely say, the US economy has increased over the past 100 years.
If however you were searching for actual evidence to their assertion about income inequality, none is found, none is offered.
Which by itself might seem trivial, if you skip the tens of thousands of people who read MotherJones daily. But even worse, respected economist Robert Shiller when discussing books pushes the MotherJone’s version of things too (article here):
….the politics that lead to rising inequality. That’s been a trend in recent years in most nations of the world. Inequality has been getting worse, particularly in the US, but also in Europe and Asia and many other places.
He even mentions the idea of having the government setup a “choice architectural” because of evidence demonstrating too many irrational decisions made on behalf individuals. Which of course assumes the government and smart economists could ever replace the collective knowledge of the market, even with irrational actors, with their own ideas or some perfect formula.
But I digress. The main issue is they give no reason to believe their assertion is true, yet act like it. Even with easily found research, with real numbers and everything, from a very reputable source, which as you likely guessed by now, states otherwise (here via NBER):
Changes in labor’s share of income play no role in rising inequality of labor income: by one measure, labor’s income share was almost the same in 2007 as in 1950.
They go on to discuss reasons inequality exists and discuss things like life expectancy, the difference between the rich and the super rich (say high level executives versus CEOs), but of course when one is looking, it’s not hard to find other evidence MotherJone’s is wrong & they have a nice little graph too (here via Wiki):
Doesn’t seem all that “increasingly skewed” to me, but I have been told I see things differently before…
& certainly some may see this distribution as unfair even if it hasn’t been increasingly skewed recently, but they will fail in their attempts to solve this problem for the same reason Mr. Shiller’s belief in the idea of a “choice architecture” will fail. They simply don’t have the knowledge required, regardless of intellect or brilliance, to supplant an answer supplied by countless independent actions taken freely (mostly) by countless individuals. It’s simple arrogance.
As Hayek stated so brilliantly:
To act on the belief that we possess the knowledge and the power which enable us to shape the processes of society entirely to our liking, knowledge which in fact we do not possess, is likely to make us do much harm.
