It's a worthwhile question and one worth comparing to the US today. Why is a sizable percentage of the US today afraid of immigrants despite no significant increase in immigration at all (unlike Europe)? In this case, assimilation is irrelevant yet this fear of immigration has been enough to put Trump in office. It's speculation, but I think rural populations worldwide are experiencing poor economic conditions while the urban areas have enjoyed growth and prosperity. The primary reason for this is most likely that young and educated people move to the cities draining rural areas of talent. Further, rural industries in first world countries are no longer competitive enough to sustain rural economies. There's more than can be said here I'm sure.
