We cannot take in all the people in the world who want to come to Sweden. But we should have generous rules for the immigration of those who risk various forms of political, religious or other uncivilized persecution.
Then it should be possible to have increased labor immigration as long as it is monitored that this does not exclude those who already have Swedish citizenship from the labor market.
But the integration policy must be improved. An immigrant should only be allowed to keep those religious and cultural characteristics that do not conflict with Swedish law. Female genital mutilation and honor killing must e.g. be fought.
Then you should focus on immigrants getting work, e.g. by combining SFI studies with internships. When immigrants could get jobs more easily in the past, they learned Swedish in the workplace quite quickly. If today they got an internship, maybe the same effect could be achieved.
