Inequality is growing for more than 70 per cent of the global population, exacerbating the risks of divisions and hampering economic and social development. But the rise is far from inevitable and can be tackled at a national and international level, says a flagship study released by the UN on Tuesday.
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 one per cent’ winners take (almost) all
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.
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.
