I'm a Russian Jew so I think I'm the scammiest of all.
In all honesty, I grew up in a Russian community and although there are scammers (insurance fraud type stuff is rampant in my parents' zipcode), the vast majority are decent people. It's all about how you're raised. My parents came to America, assimilated, and raised us to work honestly for our money. My mom always asks me if what I do for work is legal, heh.
