Growing up, I got a strong taste of that culture--there were many positive aspects, but a common negative theme that permeated my childhood was that you should never trust anyone outside of your extended family. The world was filled with con-artists trying to scam you.
About 15 years ago, a relatively large company offered to purchase my small business and 'acqui-hire' me. As I considered the offer, my parents were convinced it was a 'trick.'
"Don't let them trick you! I'm very worried about this. I don't trust them." etc. etc.
They couldn't fathom the idea that someone would willing pay me (and hire me) for something I created.
I remember thinking my parents were naive ... "We're in the USA! This is the land of optimism and positivity. It's not 1940s Italy filled with brigands and charlatans."
It's now quite sobering to me that we seem headed back to the culture that shaped my parents' worldview.
