Portes is Principal Research Fellow, formerly Director, at the National Institute for Social and Economic Research in London. From 2002 to 2008, he was chief economist at the U.K. Department of Works and Pensions and, following that, chief economist at the Cabinet Office. David Goodhart has described Portes as "one of the architects of Labour's immigration policy" during that period. He is a regular contributor to the Guardian, frequently on migration issues.
In a 2012 blog post, Portes fondly reminisced that explaining the lump-of-labour fallacy "to six successive Secretaries of State for Work and Pensions, usually in the context of immigration… was probably the most useful thing I did, from a public policy perspective, in my six years as Chief Economist at Department for Work and Pensions." The lump-of-labour fallacy is the spurious claim that supporters of some policy or other are motivated by a false belief that there is only ever a "certain amount" of work to be done.
The alleged belief is indeed false, as is the claim that support for the policy in question is motivated by it. The bogus fallacy claim was a staple of 19th century anti-trades union propaganda. Portes thus prided himself on his acumen in persuading Labour cabinet secretaries "to go out and defend policies that were consistent with" an archaic, reactionary view of the labour market.
That is not to say that the policies defended by cabinet secretaries coached by Portes were reactionary. The phrase "were consistent with" is notoriously ambiguous. Wearing an amulet is "consistent with" being a Satanist. It is also consistent with not being a Satanist. One must always be wary of "affirming the consequent."
