Explain social factor influence on phonology

study is based on sociolinguistics belief that \”level of education\” as a social factor influence the \”pronunciation of consonants\”…my study examines how this factor could influence the pronunciation of Arabic students learning English as a foreign language..
In sociolinguistics, as Labov, indicated this is a very important factor that has an influence on pronunciation…….
It makes sense because the more educated the people are, the more accurate their pronunciation become?
