She saying that they have no Personality, no education and no "Class"..People who actually know their own "worth" really don’t act this like this, they don't criticise other's Backgrounds those who themselves are insecure and unconfident show such behavior..I don't know how people by letting others down can feel "Classy" i mean it damages them more than it could create damage to others.

What is the art of being so "Educated?? and having so much exposure when you don't have basic humanity level, when you don't know the true meaning of life..If your Education and Exposure make you so inhumane that you let down others on the basis of their background then trust me having no exposure is a "Blessing"..Only classless people talk about class because that's the only way they can show their "Worth"..You are a mirror you see around what you are having in yourself so if you think people are classless then it is clear that you yourself are lacking class in yourself
