This is a very deep rooted idea in American culture, the kill or be killed, you screw someone over before they screw you over mentality. It's actually something people from Europe need to learn about to be successful in business negotiations with American firms, as there are certain boundaries that we don't cross for cultural reasons and so we don't tend to take a negotiation all the way to the logical extreme and we lose out as a result.
I assume you've never been involved in many high level American business negotiations. Because in the real world it's nothing like that. Regardless of cultural boundaries, the most profitable business relationships last for many years so it just doesn't pay to screw the other side over.
The only major exception is perhaps for certain limited sectors of the finance industry where derivatives contacts are understood to be a zero sum game. So everyone looks for clever ways to screw their trading partners. But European financial firms are just as ruthless as their American counterparts. In fact the Europeans have often been more willing to cross ethical lines.
You're either lying through your teeth or using a very, very creative definition of "Europe" that excludes most of everything that once took orders from either Rome or Moscow.
Having to distrust your business partners is not uniquely American in the slightest.
That’s not how it actually works. Most businesses work together for many years and it is a win-win situation. If you screw over your business partners you will very quickly run out of partners to work with.
