How so? Immigration at mass is at least a culture shock, a great shift in political power, and a great import of unfamiliar language. Sometimes it leads to a shift in crime rate, the abuses of the refugee system and physical conflicts between cultural groups. The immigration groups often have a lesser education background when compared to the local residents.
