How Should Wealth Should be Distributed (Part Three}

Here's my last post on the inequality of wealth distribution (previous posts here and here).  Maybe it should have been my first post, since it provides a rationale why you should care about inequality of wealth distribution.  Some would say you should care on moral grounds.  Others argue that inequality is also detrimental on economic grounds.  In other words, no matter which side of the political divide you inhabit, this is something you should care about.

Nobel Prize winner Joseph Stiglitz's recent book The Price of Inequality examines these reasons.  He argues that the current economic malaise and poor prospects of the middle and lower classes in the US are not a result of economic forces beyond America's control, but of the exercise of political power by moneyed interests over legislative and regulatory processes**:


"While there may be underlying economic forces at play, politics have shaped the market, and shaped it in ways that advantage the top at the expense of the rest".  


In his New York Times opinion piece entitled Inequality is Holding Back the Recovery, Stiglitz argues persuasively that economic inequality is squelching recovery because it means that tax receipts are down, economic volatility is up, and the middle class is too weak to support consumer spending and cannot invest in the future (education or businesses).




Although the US sits 91st of 153 countries on its wealth distribution (as described in this post), it feels as if Stiglitz is pushing a rock uphill in raising the issue of inequality, when you look at the general political debate in the US.


Ironically, Germany which sits 13th on the list (with wealth inequality declining) has seen inequality emerge as an election issue, as described in this Economist article***.  Germany had a huge increase in inequality with the integration of East Germany, but the gap between East and West Germany is shrinking.



Often, wealth inequality in the US is justified on the basis that the people at the top earned their money through hard work in a land of equal opportunity.  Indeed, t|he US cherishes its image as a utopia of meritocracy: anybody who works hard can make it.  The facts show otherwise: not only is there greater inequality in the US than in most developed nations, but this inequality is persistent.  Children in other rich countries like Canada, Germany, France and Sweden have a better chance of doing better than their parents than American children*.  A New York Times article reported that at least five large studies showed the US to have less mobility than comparable nations: Canada, Norway, Finland and Denmark all showed greater mobility.  A Globe and Mail headline boasted "In Canada, unlike the US, the American dream lives on".




*  I've taken that fact from Stiglitz' column
** phrasing directly taken from NYT book review of this book
*** According to The Economist, Germany sits at 7th, rather than 13th position as my data claimed.  That data showed German data from 2000, so it makes considerable sense that Germany has risen since then.  I chose to characterize Germany at 13th to be consistent with previous post.

How Should Wealth be Distributed (Part Two)

In my last post, I opened the subject of income inequality.  This topic of income and wealth inequality has been fascinating me lately, and I'm not alone in this fascination as growing wealth disparity is gaining more and more press attention.

The most common way to measure income inequality is using the Gini coefficient described here. There's quite a bit of math behind the calculation of the index, but, in simple terms, a country Gini index of 100 indicates perfect inequality (i.e. one person owns all the wealth) while 0 indicates perfect equality (i.e. wealth is evenly distributed among all).  Wolfram Alpha has a histogram showing the distribution of the Gini index across the world.

I was curious about the degree of wealth inequality in various nations around the world.  This reference* shows the Gini index for 153 countries around the world with, the Seychelles at the bottom of the inequality list with a coefficient of 65.77, and Denmark at the top with a coefficient of 24.70.  Not surprisingly, the ten countries showing the greatest inequality are all relatively poor - the Comoros, Namibia, South Africa, Botswana, Haiti, Angola, Honduras, Central African Republic, and Bolivia.

Three of the four countries with the lowest Gini coefficient - i.e. with the most equal distribution of wealth - are not, surprisingly, Scandinavian: Denmark (24.70), followed closely by Japan (24.85), Sweden (25) and Norway (25.9). The Czech Republic (25.82) rounds out the top 5.

I reflected on how this might play out in real life.  When visiting Kenya and Tanzania a few years ago, I observed that ordinary Tanzanians seemed to be much better off than Kenyans, despite a substantially higher per capita GDP in Kenya than in Tanzania ($808 versus $532).  Well, on the Gini list, Kenya (at 47.68) is near the bottom at 120th of 153, while Tanzania (at 37.58) is just above the middle at 67th, a full 53 positions higher than Kenya.  So, from my own small, personal, totally unscientific sample, you can actually see the difference distribution of wealth can make.

How does North America fare?  Canada (32.56) is 30th of 153.  Mexico (48.28) is almost tied with Kenya at 122nd.  So where might the US be, the richest country in the world?  The US** (40.81) is a dismal 91st : i.e. it's in the bottom half of the world when it comes to inequality and it's about half way between Kenya and Tanzania.

The next question to ask is whether this matters very much.  What's your opinion of how wealth should be distributed in your country?

* I should point out that in this chart I found, the coefficients relate to different years in different countries, so they are not directly comparable.

** This figure dates from 2000, and recent data points to a deteriorating situation re inequality since then.

How Should Wealth be Distributed? (Part One)

US Wealth Distribution 

Recent research by Harvard's Michael Norton and Duke's Dan Ariely (described here) reported on a survey of respondents' views on how wealth should ideally be distributed (column 1), their perception of how wealth is distributed (column 2), and how wealth really is distributed (column 3).

There's stunning divergence between these charts.  People feel wealth should be fairly equally distributed.  They perceive that wealth is not distributed that equally, but that it's in the ball park.  However, they miss the fact that wealth is distributed much much more unequally than they perceive.

Wealth is extremely unevenly distributed in the US.  The top 1% hold 40% of the wealth, and the top 20% hold over 80% of the wealth.  Yet a random sample of 5,000 Americans perceive that the top 20% hold just over 50% of the wealth, and they feel that, ideally, they should hold about 30% of the wealth.

The research has provoked discussion on the topic, and has also spawned a video that expresses the data more visually which will appeal to those less comfortable with simple percentages and statistics.

The reason for this misperception among Americans might be explained by some of Dan Ariely's previous work in behavioural economics.  Dan Ariely is best known for his book Predictably Irrational.  It's a great read and I highly recommend it.  (I've written about Ariely's work before in posts here, here, and here.)  Ariely's research highlights the many behaviours exhibited by humans that are simply not rational.

One of Ariely's key points is that people assess choices in comparison to easily comparable choices in their own environment.  So one could postulate that people have a distorted perception of wealth distribution because they mostly pay attention to the people around them, people likely to enjoy similar levels of wealth to their own.  Then they extrapolate from that experience and assume the whole country exhibits a similarly flat wealth distribution.  They are also misled by evaluating people's wealth based on their apparent material possessions, yet one family might own their McMansion outright while the family next door is drowning in debt.

The survey did not uncover a big difference in attitude between those who voted Republican and those who voted Democratic.  They had a remarkably similar view on how wealth should be distributed.  American politics can be very puzzling to non-Americans.  If people voted purely based on their economic self-interest, then the top 1% - or let's be generous and say the top 20% - would vote Republican and the rest would vote Democratic.  However, we don't see those voting patterns.  Puzzling.

* For those interested in this topic, there's a second post on this topic here.
