I tried to be as polite as possible with my question:
Me: There are a lot of scammers in my business but for some reason, percentage wise, there appear to be more crooked Russians than any other Nationality. Why is that?"
My Russian friend: Because they are Russian. Russians will screw over Non-Russians in a heartbeat especially if the other person is an American. Russians, even those in America, hate most Americans.
There were 25 of us at the table. 23 were Russian and they all agreed.
