The document discusses social investment policies in the EU in light of concerns over competitiveness, inequality, and unemployment. It argues that welfare states need to focus on developing "stocks" of human capital, easing labor market "flows", and maintaining strong minimum income "buffers". Countries with effective vocational education and training systems that recalibrate these three functions outperform others. The EU faces challenges from policy legacies, divergence between members, and insecure futures that undermine its viability, calling for a social investment agenda to foster inclusive growth for economic, social and political reasons.
