Finally managed to read Philippe Legrain’s book Immigrants (2007). Strong case for benefits of immigration. Many good and eye-opening points, but some cases are not that applicable (Israel’s immigration policy for example – integration might be easier if religion a unifying factor). Legrain proposes “tax” on working visas – immigrants could apply for 3-4 year working visa and get it by paying a set fee. This fee would be different depending from which country applicant is coming from.
