MigrationWatch has argued that, while limited skilled migration (in both directions) is a natural and beneficial feature of an open economy, very large scale immigration is of little benefit to the indigenous population. MigrationWatch has claimed that migration into the UK has and will tend to hold down the real wages of British citizens. In 2006 it expressed concern that immigration from Eastern Europe was depressing wages. In December 2008, a MigrationWatch report stated that while some immigration results in an increase in the number of people in employment, "it seems an inescapable conclusion that the sudden arrival of a very large number of very capable workers willing to work for low pay has had a negative impact on the employment of British-born workers at the bottom of the pay scale". Will Somerville and Madeleine Sumption of the Washington, D.C.-based Migration Policy Institute state in an Equality and Human Rights Commission report that: "Few serious international or UK economists would agree with this conclusion". Their report did, however, note that "the recent migration may have reduced wages slightly at the bottom end of the labour market, especially for certain groups of vulnerable workers".
