This book addresses the central challenge facing rich countries: how to ensure that ordinary working families see their living standards and the prospects for their children improve rather than stagnate over time. It presents the findings from a comprehensive analysis of performance over recent decades across the rich countries of the OECD, in terms of real income growth around and below the middle. It relates this performance to overall economic growth, exploring why these often diverge substantially, and to the different models of capitalism or economic growth embedded in different countries. In-depth comparative and UK-focused analyses also focus on wages and the labour market and on the role of redistribution. Going beyond income, other indicators and aspects of living standards are also incorporated including non-monetary indicators of deprivation and financial strain, wealth and its distribution, and intergenerational mobility. By looking across this broad canvas, the book teases out how ordinary households have fared in recent decades in these critically important respects, and how that should inform the quest for inclusive growth and prosperity.
