Will Wilkinson’s recent paper on income inequality argues that it’s an overrated problem (see also here). Before I deal with his arguments in detail, a quick reminder of my personal views on income inequality. From the point of view of human rights (which is my default starting point), the most urgent problem is not necessarily the unequal distribution of wealth or income, but the insufficient wealth and income of the poor in a given population. The urgent problem is absolute poverty, rather than relative poverty. Or, in other words, what we have to tackle first is some people’s inability to gather sufficient resources necessary to survive in a decent way, not the fact that some people have more resources than others. The human rights of people in a very poor but highly egalitarian society can be violated more extensively than the human rights of the relatively poor in a society that is very rich on average but highly inegalitarian. Eliminating or reducing income inequality – or “killing the rich” (metaphorically) as in the image above – doesn’t necessarily help the poor.
However, inequality can be a problem. The absence of poverty or the availability of sufficient resources for a decent human life is a human right, but it isn’t the only human right (some would even say that it isn’t a right at all, but I disagree, together with the drafters of the Universal Declaration). Human rights also include political human rights, and these political human rights usually mean the right to democratic participation in government and legislation. Income inequality makes these political rights highly problematic. Democracy is based on the equal influence of every citizen, but income inequality, by definition, gives the wealthier citizens more influence in politics.
In addition, income inequality may also lead to social fragmentation, with negative consequences for the cohesiveness of a society. We see that highly inegalitarian societies, such as the U.S., are also societies with relatively low levels of social mobility. One could argue that income inequality isn’t much of a problem when everyone has the same chance to be on the good side of the inequality. But when it is combined with social rigidity and stratification, it undermines meritocracy and equality of opportunity, which in turn enhances social fragmentation.
Finally, people in more egalitarian societies tend to be healthier, to live longer and to be happier (as Wilkinson should know).
These are serious issues from the point of view of human rights. If reducing income inequality (for example through progressive taxation, public spending – on welfare, education, healthcare etc. – and regulation of political funding and lobbying) can go some way towards a solution, we should consider it.
One last point: all these issues are based on the assumption that income inequality is the outcome of just processes. In other words, we assume that people’s incomes are the result of their own desert and effort. If, on the other hand, we assume – more correctly in my view – that income and wealth distributions are affected by unjust processes (such as colonialism, slavery, discrimination, inheritance and a lack of social mobility etc.) than we have additional reasons to do something about income inequality. And these reasons have nothing to do with the negative consequences of inequality. They are, instead, related to its origins.
(If you want to know more about my views on income inequality, before I tackle Wilkinson’s views, you can read this old post).
Wilkinson claims that
income inequality is a dangerous distraction from the real problems: poverty, lack of economic opportunity, and systemic injustice.
Those are real problems indeed, and even more urgent problems, as I’ve stated above. But income inequality is also a real problem, and I fail to see how one problem is necessarily a distraction from another problem. Human beings are perfectly capable of tackling several problems at the same time.
He also states that
there is little evidence that high levels of income inequality lead down a slippery slope to the destruction of democracy and rule by the rich.
That’s not true, as you can read here and here. Income inequality obviously doesn’t necessarily “destroy” democracy or replace it with “plutocracy”, but it significantly reduces its meaning, on both sides of the income gap: wealthy people use their wealth, their higher education, their networks etc. to gain influence, and poor people tend to participate less and thereby lose influence. While it’s true that wealthy people can use their political influence for the benefit of their poor fellow-citizens, it’s still a fact that many don’t. If we cherish democracy, we should implement policies that limit the risk of selfish interventions by disproportionately influential individuals or groups, as well as policies that encourage participation of relatively less influential individuals and groups. It’s not sufficient, as Wilkinson does, to point to the fact that many wealthy people voted for Obama, knowing that he would raise their taxes.
Wilkinson also believes that the level of American income inequality was not caused by exploitative, institutional mechanisms. Given the historical inheritance of slavery and discrimination, I think this opinion is false. This inheritance, combined with astonishingly high levels of correlation between parental income and the income of children, does suggest that there are institutional mechanisms which perpetuate income inequality. While it’s wrong to claim that the inheritance of racism and slavery is to blame for the poverty of African-Americans living today, it’s very likely that it has some effect.
Few people argue for a completely egalitarian society. I certainly don’t. Some inequalities are perfectly just, and probably necessary from the point of view of economic efficiency. But there are many who argue for the opposite: don’t do anything about inequality. While I don’t believe Wilkinson is one of them, his statement that “income inequality is a dangerous distraction” encourages those who believe that we shouldn’t care about inequality.
