There are such people ~ they get screwed by the same crowd.
I suspect things were not better back in the days when the Persians were still picking lice off each other's furry backs sitting in caves! That ethical standard is argued, by some, to be a necessary component of desert life.
Like Pryce-Jones, in his “Closed Circle”.
And in fact, you see more and more of this mentality in wider socialist circles.
Ok, so I’ll lay out some of my experiences.
As a Stockbroker in the early 1990’s, one of my best clients was Iranian. We never spoke of politics, it was simply me giving him advice on what and when to buy and sell.
He sent me a client, an Iranian friend, that opened an account and proceed to disregard all my advice and lost a boat load of money. There was always something different about our conversations during this time. He found himself not only losing a lot of money, he actually owed us money because his account went, negative equity. The firm I worked for was resigned to write it off since the cost to go after him was greater than the debt. This guy, turned around and tried to sue us for his loss. We counter sued and I went to court and watched as the judge imposed a monetary judgment against him.
A few years later, I was running a daytrading office and a deep pocketed trader brought in a buddy to trade with him. It turned out that this new guy was related to the guy from a few years back. I let him open an account and trade before his check (a bank check), for $50,000 cleared. He traded all on his own for three days and lost $13,000 and disappeared. He stopped payment on the check and left me high and dry. After consulting with others, it made no sense to go after him.
I know things are different now, but there was a time that when you had a verbal agreement to conduct business it meant something.
I will never trust Arabs/Persians/Muslims ever again.
It is their responsibility to earn my trust.
