I work with a Russian girl that judges Americans harshly. Is this typical?

We work very closely together and at first, she came off almost rude, but as I’m very agreeable, became friends. She often says horrible things about America, but most I agree with. Recently, she said the biggest issue with Americans is how they have a “this is good enough” mindset while Russians are always striving to do and be better. She said when she moved to America, it was shocking to her family that we did not have a perfectionist attitude. Recently she said she has come to work looking like a bum lately, although she dresses and puts so much into her looks and I dont.

At times, i feel very judged by her, but she has invited me over and acts as though shes a friend.

Is this typical of Russians?
