A 2005 report commissioned by the Sutton Trust revealed that the UK, alongside the United States, has the lowest level of social mobility of any developed country for which there is data. Researchers from the London School of Economics found that one reason for this trend was that the expansion of higher education in the UK disproportionately benefited those from better-off backgrounds. A follow-up report by the LSE group in 2008 concluded that social mobility had levelled off, with children born in 2000 facing the same mobility prospects as those children born 30 years earlier.
