How inequality affects economic growth

Inequality in income and wealth can slow down the overall expansion of an economy. Studies from organisations like the Organisation for Economic Co-operation and Development (OECD) and the International Monetary Fund (IMF) indicate that increasing inequality has reduced gross domestic product (GDP) by about 7% in OECD nations. This happens because inequality limits opportunities for many people, which in turn affects productivity and investment levels.

Ways inequality reduces economic growth

• Limited access to essential services - People with lower incomes often cannot afford proper healthcare or education, which prevents the development of skills and knowledge needed for a strong workforce.
• Lower productivity from poor education - Children from disadvantaged backgrounds may go to under-resourced schools and have less chance of higher education, resulting in a less skilled labour force and slower increases in output.
• Decreased savings and investment - Inequality squeezes the middle class, who usually save the most, while richer groups might spend on imported luxuries or send money overseas, leading to less money available for domestic investments that could improve resources and technology.
• Rent-seeking activities - This involves efforts by wealthy individuals to secure a bigger portion of existing resources through influencing rules, rather than creating new value, which diverts effort away from activities that could expand the economy.
• Restricted access to finance - High inequality means fewer people can get loans or credit, stopping them from investing in education for their children or launching new enterprises.
• Fragile and non-inclusive expansion - When benefits are concentrated among the rich, growth is less stable and more vulnerable to setbacks, as it does not involve the whole population.
• Instability that discourages investment - Divisions caused by inequality can create political and social unrest, making businesses hesitant to invest, and governments struggle to agree on solutions during economic difficulties.

The effects of inequality on standards of living and social stability

High levels of inequality create broader problems that make life harder for everyone in society. It leads to higher social costs and can make communities less safe and cohesive, affecting overall well-being.

Social and stability issues caused by inequality

• Higher crime levels - Disadvantaged groups are more likely to be involved in or affected by criminal activities, increasing insecurity for all.
• Erosion of trust and cohesion - Inequality damages faith in organisations and weakens the bonds that hold society together.
• Resistance to positive changes - Powerful groups with wealth often block reforms that would benefit everyone, as they protect their own interests.
• Support for extreme policies - People facing hardship might back radical or harmful political ideas in response to their situation.
• Concentration of influence - Wealthy individuals gain more control over decisions, often shaping outcomes to favour themselves rather than the wider public.
• Risk of major disruptions - Extreme differences can spark conflicts or uprisings, leading to loss of life and setbacks in development.

Key pathways linking inequality to economic and social issues

Inequality influences economies and societies through several connected routes. These pathways show how gaps in income and wealth create ongoing cycles of disadvantage and instability.
