I’d disagree. I’m not American or British but and in my experience Americans or British are the least ethnically biased people on the planet. Any other group, I could believe that they are biased but not Americans, or British. Something in their particular culture right now.
It isn’t just a lack of ethnic bias, it’s a belief in capitalism or professionalism or “enlightened self-interest”: hire the best person for the job, and everyone will be better off.
Yes that's why country clubs and the Greek system never caught on...
You’re responding to an American who says he’d be biased towards Americans and telling him he’s wrong.
Maybe Americans are the least biased (though being an American I am not so sure) but that doesn’t mean we aren’t biased (even if sometimes for legitimate reasons like ease of communication).
