Inequality is not a cause of crime

Following the release of South Africa’s 2018 crime statistics, which police minister Bheki Cele described as a “war zone”, there was a side discussion by some opinion writers that “inequality” is a cause of crime.

Many people – politicians, business, journalists and worst of all academics who should know better – confuse and conflate inequality with poverty. They are linked but not the same.  Poverty is the shortage or absence of livelihood resources and assets particularly income/money, and inequality the disparity of wealth (income) in a society. Poverty affects the individual at micro level whereas inequality is a macro, notional indicator of social or income equilibrium – the social democratic ideal.

Inequality is a catch-all red herring to describe SA's ills. People use it, often loosely, to sound knowledgeable, as a sound bite, to simplify what they're talking about or out of intellectual laziness, in this case, the cause of crime.

Inequality does not drive a person to commit crime but a variety of reasons do including need, psycho-pathologies, opportunity, and the main motives for murder, power, money, sex, recidivism, career criminality, etc.  Poor people are not more prone to commit crimes than those who are not.  If that was the case there wouldn’t be white collar crime, theft, fraud and corruption where well-heeled businessmen, politicians and the like skim money off the top and take pensioners savings.  

But I suppose if the circumstances were ripe, a person who hasn’t eaten for days or similarly desperate can commit a crime to serve that need. However, the poor around us – we see them every day – don’t necessarily commit crimes – most of them are law abiding – which go to show poverty it’s not the only driver.  It contributes certainly, but who knows by how much.  Perhaps a troubled society like South Africa has a higher proportion of sociopaths, psychopaths and recidivists as evidenced by its high crime and murder rates.

A person contemplating committing a crime will do so out of a real or perceived need, except career criminals, sociopaths and psychopaths who do so for the thrill of the crime itself and for profit like the conman who recently defrauded my credit card.  He or she doesn’t say, “You know, society is so unequal ("inequality”) that I’m going to correct that. The Robin Hood “good thief” legend of stealing from the rich to give to the poor is just that.

The poor are as law-abiding as the rest of the population and are no more likely to commit crime than anyone else all things being equal. It's an insult to them and rubbish and speculation to suggest that.

Poverty (inequality, which is a notional term like GDP per capita, is often used to make a political rather than practical point, and by people who have no idea what it means) and need might drive desperate people to commit crime, but the brutality in South Africa that accompanies it speaks of something else - evil and utter disregard for life and law. It's not about income equality.

So I disagree with those who say inequality contributes to crime because the term itself is used incorrectly in place of “poverty” and it inaccurately attributes the effects of poverty – lack of basic goods.  Incidentally, the poor are also victims of property crimes within their communities which disproves the blanket assumption wealth disparity increases the incidence of it.

In a The Conversation article University of Cape Town doctoral candidate Anine Kriegler wrote “inequality makes property crime more attractive and profitable, and drives frustration, hostility and hopelessness”.  (She also said it “undermines trust, community engagement and the functioning of social and institutional structures” which I have no issue with.)

In a follow-up comment she said: “The countries with the highest murder rates are the middle-income ones that show large disparities in wealth”.

I tested this assertion. I looked at lists of the 100 middle-income countries and cross-referenced it with 100 countries with the highest income inequality (Gini coefficients) and highest murder rates per 100,000 population. I couldn't determine what a “high” Gini is so assumed it’s 40 (0-100%) and over. Similarly, I can’t find a definition a “high” murder rate so assumed anything above 10 per 100,000. See Table 1.

There’s no Gini data for 17 countries (only four of those have murder rates above 10), so let’s exclude them. Of the remaining 83, India’s Gini is 8.6 and the rest range from 25.5 to 63.4, the highest, for South Africa (murder rate 34). Only 20 countries have murder rates above 10, from 10.4 (Papua New Guinea; Gini 43.9) to El Salvador’s 82.8 murder rate (Gini 40.8).

While the average Gini for the 83 countries is 39.8, murder rates start at a low 0.5, 45 with murder rates below 5.

Therefore, there’s no statistical correlation between high inequality and high murder rates. Of course, this analysis doesn’t examine countries’ unique social conditions that may account for their crime and murder rates.

I've not read the studies by "people who have dedicated their lives to the field", i.e., academics like her Kriegler that referred to, and perhaps I shall.  But I can’t believe researchers haven’t done this breakdown, a basic first step.

Without having read the international studies she mentioned, I’m sceptical of their conclusions. My superficial assessment supports what I said that inequality is not a driver for crime, and using macro indicators is misleading if not incorrect. Inequality is an outcome like crime itself of the causal chain rather than a claimed trigger:

Political & business environment > Poor or inappropriate economic policies & practices > Lack of medium-long-term economic growth and development > Lack of medium-long-term economic growth & development > Poverty or unmet basic needs > Inequality & other negative societal conditions.

The causes of crime cannot be generalised to one convenient factor because social dynamics and pressures vary from one country to another and within a country, from one city or community another.
