In this note it is shown that the different attitudes towards immigration c
an be explained in terms of economic interest, although the public immigrat
ion debate is dominated by moral and political arguments. On the one hand,
immigration supporters are mainly found among those who may expect economic
gains from immigration - skilled workers and especially members of certain
professions. On the other hand, unskilled workers who stand to lose econom
ically because they can be easily substitued for by immigrants are for the
most part opposed to immigration.
