It's very dangerous to stereotype people in the manner you do. What are "traits" of a lower class? For instance, many well-educated and rich people behave as raging assholes, are selfish and abuse others. But it's okay because they're upper class, educated and possess a random piece of paper we call a degree or diploma? Conversely, many lower class people are noble, humble and go out of their way to help others and their community. Why should you not interact with such people? Of course, you can do what you want. :)) For me personally, it does not matter what color skin someone has, what degree they hold, their sexual orientation, social class, etc...it's about character and the emotions they stir within me.
