Uneducated immigrants who can't write or read German are gonna work and pay taxes? While their social benefits are at such a level, that what they receive in a month from the state, they won't make within a year in their home countries. Perhaps the children of the immigrants will one day become productive tax paying citizens, but the costs for their education, housing and healthcare, don't make up to the potential future benefits.
