Inequality is set to become the most important issue of the 21st century.
Recognising that there are many forms of inequality: economic, social and political, progressives need to create an agenda that focuses on building job security, improving education, developing a system of pre-distribution with a greater role for social partners and unions, and a fairer tax system.
Politically, progressives should become the political voice of the middle class and lower earners. We must not focus solely on social justice, but we should also work to build solidarity and the idea of social responsibility between citizens. We must also not limit our thinking to the national level. The fight against inequality does not exist in isolation within states, and greater international co-operation will be a critical part of working to meet these challenges.
