Brexit and migration: why do rocket scientists pick strawberries?

Why do rocket scientists pick strawberries, asks Nauro F Campos (Brunel University)? He explains that there are many benefits to migration that are hard to gauge from an economic perspective. Central-Eastern European migrants, for example, who came to the UK in droves in 2004, are known to have significantly higher levels of schooling than that native workers. These migrants take on unskilled jobs because they know they are temporary, and usually enjoy rapid career progression, he argues.
