Actually i do agree with the statement. I live near the biggest city in my state and my friends are different in ideas, political opinions and preferences (also kinda different in economic possibilities) due to the fact that we all went to the same highschool, and there are few places where the young can socialize. on the contrary my brother lives in that big city and its friends are ALL coming from the same cultural background, with the same ideas and the same political leaning (that he chooses during university)

A lot of that has to do with the fact that you chose your friend group during public high school and he chose his during university, which itself already selects for the upper socioeconomic statuses.
