The World Social Report 2020, published by the UN Department of Economic and Social Affairs (DESA), shows that income inequality has increased in most developed countries, and some middle-income countries - including China, which has the world’s fastest growing economy.

The challenges are underscored by UN chief António Guterres in the foreword, in which he states that the world is confronting “the harsh realities of a deeply unequal global landscape”, in which economic woes, inequalities and job insecurity have led to mass protests in both developed and developing countries.

“Income disparities and a lack of opportunities”, he writes, “are creating a vicious cycle of inequality, frustration and discontent across generations.”

The study shows that the richest one per cent of the population are the big winners in the changing global economy, increasing their share of income between 1990 and 2015, while at the other end of the scale, the bottom 40 per cent earned less than a quarter of income in all countries surveyed.

One of the consequences of inequality within societies, notes the report, is slower economic growth. In unequal societies, with wide disparities in areas such as health care and education, people are more likely to remain trapped in poverty, across several generations.

Between countries, the difference in average incomes is reducing, with China and other Asian nations driving growth in the global economy. Nevertheless, there are still stark differences between the richest and poorest countries and regions: the average income in North America, for example, is 16 times higher than that of people in Sub-Saharan Africa.

Four global forces affecting inequality

The report looks at the impact that four powerful global forces, or megatrends, are having on inequality around the world: technological innovation, climate change, urbanization and international migration.

Whilst technological innovation can support economic growth, offering new possibilities in fields such as health care, education, communication and productivity, there is also evidence to show that it can lead to increased wage inequality, and displace workers.

Rapid advances in areas such as biology and genetics, as well as robotics and artificial intelligence, are transforming societies at pace. New technology has the potential to eliminate entire categories of jobs but, equally, may generate entirely new jobs and innovations.

For now, however, highly skilled workers are reaping the benefits of the so-called “fourth industrial revolution”, whilst low-skilled and middle-skilled workers engaged in routine manual and cognitive tasks, are seeing their opportunities shrink.

Opportunities in a crisis

As the UN’s 2020 report on the global economy showed last Thursday, the climate crisis is having a negative impact on quality of life, and vulnerable populations are bearing the brunt of environmental degradation and extreme weather events. Climate change, according to the World Social Report, is making the world’s poorest countries even poorer, and could reverse progress made in reducing inequality among countries.

If action to tackle the climate crisis progresses as hoped, there will be job losses in carbon-intensive sectors, such as the coal industry, but the “greening” of the global economy could result in overall net employment gains, with the creation of many new jobs worldwide.

For the first time in history, more people live in urban than rural areas, a trend that is expected to continue over the coming years. Although cities drive economic growth, they are more unequal than rural areas, with the extremely wealthy living alongside the very poor.

The scale of inequality varies widely from city to city, even within a single country: as they grow and develop, some cities have become more unequal whilst, in others, inequality has declined.

Migration a ‘powerful symbol of global inequality’

The fourth megatrend, international migration, is described as both a “powerful symbol of global inequality”, and “a force for equality under the right conditions”.

Migration within countries, notes the report, tends to increase once countries begin to develop and industrialize, and more inhabitants of middle-income countries than low-income countries migrate abroad.

International migration is seen, generally, as benefiting both migrants, their countries of origin (as money is sent home) and their host countries.

In some cases, where migrants compete for low-skilled work, wages may be pushed down, increasing inequality but, if they offer skills that are in short supply, or take on work that others are not willing to do, they can have a positive effect on unemployment.

Harness the megatrends for a better world

Despite a clear widening of the gap between the haves and have-nots worldwide, the report points out that this situation can be reversed. Although the megatrends have the potential to continue divisions in society, they can also, as the Secretary-General says in his foreword, “be harnessed for a more equitable and sustainable world”. Both national governments and international organizations have a role to play in levelling the playing field and creating a fairer world for all.

Reducing inequality should, says the report, play a central role in policy-making. This means ensuring that the potential of new technology is used to reduce poverty and create jobs; that vulnerable people grow more resilient to the effects of climate change; cities are more inclusive; and migration takes place in a safe, orderly and regular manner.

Three strategies for making countries more egalitarian are suggested in the report: the promotion of equal access to opportunities (through, for example, universal access to education); fiscal policies that include measures for social policies, such as unemployment and disability benefits; and legislation that tackles prejudice and discrimination, whilst promoting greater participation of disadvantaged groups.

While action at a national level is crucial, the report declares that “concerted, coordinated and multilateral action” is needed to tackle major challenges affecting inequality within and among countries.

The report’s authors conclude that, given the importance of international cooperation, multilateral institutions such as the UN should be strengthened and action to create a fairer world must be urgently accelerated.

The UN’s 2030 Agenda for Sustainable Development, which provides the blueprint for a better future for people and the planet, recognizes that major challenges require internationally coordinated solutions, and contains concrete and specific targets to reduce inequality, based on income.
