- In South Africa, one of the most unequal countries in the world,
- the richest one-tenth of 1%, owns almost 30% of all the country's wealth,
- more than double what the bottom 90% owns.
- Income and wealth inequality are not new.
- In fact, economists and historians who've charted economic inequality throughout history haven't found a single society without it.
- Which raises a bleak question: is inequality inevitable?
- One way to estimate inequality is with a number called the Gini index,
- which is calculated by comparing the income or wealth distribution of a perfectly equal society to the actual income or wealth distribution.
- The area of this shape multiplied by 2 is the Gini index.
- A Gini of 1 indicates perfect inequality: one person has everything and everyone else has nothing.
- You'd never see this in real life because everyone except that one person would starve.
- A Gini index of 0 indicates perfect equality: everyone has exactly the same income or wealth.
- But you also never see this in real life, not even in communist countries,
- because for one thing, that would mean paying everyone, no matter how young, old, what job they're in or where they work, the exact same wage.
- Typical after-tax Ginis in developed countries today are around 0.3,
- though there's a wide range from pretty equal to pretty unequal.
- Before we go any further, you should know what the Gini index, or any other measure of economic inequality, doesn't tell us:
- it gives no information about how income and wealth are distributed across genders, races, educational backgrounds or other demographics;
- it doesn't tell us how easy or difficult it is to escape poverty.
- And it also gives no insight as to how a particular society arrived at its present level of inequality.
- Economic inequality is deeply entangled with other types of inequality:
- for example, generations of discrimination, imperialism, and colonialism created deeply rooted power and class inequalities that persist to this day.
- But we still need at least a rough measure of who gets how much in a country.
- That's what the Gini index gives us.
- Some countries are, economically, much more unequal than others.
- And that's because a significant portion of economic inequality is the result of choices that governments make.
- Let's talk about some of these choices.
- First: what kind of economy to use.
- In the 20th century, some countries switched to socialism or communism
- for a variety of reasons, including reducing economic inequality.
- These changes did dramatically reduce economic inequality in the two largest non-capitalist economies, China and the Soviet Union,
- especially in the Soviet Union.
- But neither country prospered as much as the world's leading economies.
- So yes, people earned about as much as their neighbors did, but that wasn't very much.
- This and many other issues contributed to the Soviet Union's collapse in 1991.
- And China, to grow more quickly, shifted its economy towards capitalism starting in the late 1970s.
- What about capitalist countries?
- Can they choose to reduce economic inequality?
- It's tempting to think "no, because the whole point of capitalism is to hoard enough gold coins to be able to dive into them like Scrooge McDuck."
- China seems to provide the textbook example of this:
- after it became more capitalist, its Gini index shot up from under 0.4 to over 0.55.
- Meanwhile, its per capita yearly income jumped from the rough equivalent of $1,500 to over $13,000.
- But there are many counter examples, capitalist countries in which inequality is actually holding steady or decreasing.
- France has kept its Gini index below 0.32 since 1979.
- Ireland's Gini has been trending mostly downward since 1995.
- The Netherlands and Denmark have kept theirs below 0.28 since the 1980s.
- How do they do it?
- One way is with taxes.
- Personal income taxes in most countries are progressive:
- the more money you make, the higher your tax rate.
- And the more progressive your tax system, the more it reduces inequality.
- So, for example, while pre-tax income inequality in France is roughly the same as it is in the US,
- post-tax inequality in France is roughly 20% lower.
- Meanwhile, inheritance taxes can reduce the amount of wealth that a single family can amass over generations.
- Germany and many other European countries have inheritance or estate taxes
- that kick in at a few thousand to a few hundred thousand Euros, depending on who's inheriting.
- The US, on the other hand, lets you inherit 12 million dollars without paying any federal tax.
- Another way is with transfers:
- when the government takes tax revenues from one group of people and gives it to another.
- For example, Social Security programs tax people who work and use the revenue to support retirees.
- In Italy, about a quarter of Italians' disposable household income comes from government transfers.
- That's a lot, especially relative to the US, where the figure is just over 5%.
- A third way is to ensure that everyone has access to things like education and healthcare.
- A highly educated, healthy workforce can command a higher salary on the market, thus reducing inequality.
- The fourth way is addressing the digital divide:
- the gap between those who have access to the Internet and those who do not.
- A fifth way is dealing with extreme wealth.
- Multibillionaires can buy social media platforms, news outlets, policy think-tanks, perhaps even politicians,
- and bend them to their will, threatening the very fabric of democracy.
- We are just barely scratching the surface of inequality here.
- We haven't touched on the drastic divides in who has wealth and who doesn't;
- the power structures that prevent social and economic mobility;
- and the drastic inequality between countries:
- the fact that, for example, just three Americans have 90 billion more dollars than Egypt, a country of 100 million people.
- And here's one final thing to think about:
- power and wealth are self-reinforcing, which means that equality is not.
- Left to their own devices, societies tend toward inequality,
- unless we weaken the feedback loops of wealth and power concentration.
