What I mean is being uncultured, not necessarily evil.
This is often the case with people who have recently climbed the socio-economical ladder and newly gained huge wealth in a short amount of time, without developing the culture and character. In my native language we have a term to describe these people who lose themselves when they become rich but in English I haven't encountered such a categorization.
Edit: Please stop making false accusations against me. I agree that these examples may be inappropriate but I have no intention of humiliating any race or class in this question. You can read my answers in the comments below this question.
Edit 2: I removed the examples.
