economy2030 (january 2022) The UK is facing a decade of unprecedented economic change as we adjust to a post-Covid-19 economy, a new economic context outside the European Union (EU), and the decarbonisation of the economy.  And the social security system has a key role to play in the years ahead: it is part of the policy toolkit for helping individuals and the economy as a whole deal with a period of enhanced labour market change, but it also needs to address the legacy problems of slow growth in living standards and high inequality. This report considers how well the UK’s social security system for working-age households is equipped to meet these challenges, and, in particular, how well aligned it is with the country’s likely future economic and social challenges.
