They have to encourage it. Their economies would collapse otherwise. Too many lazy stupid white people in those countries who wont or cant do the jobs so immigration is needed.
In that case, they should be encouraging the skilled migration. On the other hand, most of the immigrants who end up in Europe are the illiterate types. And I disagree with your argument that
lazy stupid white people in those countries wont do certain types of jobs. These jobs are done by white people only (although they are from Poland and Lithuania). Most of the Arab and other immigrants hardly contribute anything positive to the European economies.
