Do you have any data on this? I think it just depends on the country. I was born in Italy, very low trust: the culture is that when a person is interacting with you, you have to assume they are trying to scam you.
Moved to Canada, heavy culture mix yet that "scam feeling" is gone, trust feels higher across the board.
