I'm curious how this is developing for you. It sounds like one of those decisions where maybe you can never quite have enough information -- even if you seem to have too much. At some point, you may have to go with your gut.
I think I would look closely at what the business is, and how it fits in the global economy now. Hopefully this was given some consideration before and it isn't a big IF in the recession. Just thinking, there have been some pretty drastic changes from the "average" American perspective in the past few years. I don't know if the overall economic situation might have changed the outlook for the industry you're working with.
There are quite a few people looking for a job, if you could entrust someone else to manage it. Again though, it depends on the particulars.
Personally, I don't have a very clear picture of what Russia is like now. I don't know the culture that well. Maybe in the US people smile more and drink a bit less? Laughs. Yes, I only know simple things. Our working class has some concept of hardship, but the middle seems to be just getting a taste recently. I don't think either precisely compares to all that the USSR or earlier post-Soviet Russia went through (if that is on your cultural radar at all).
From another angle, though... I really think it depends what you come here for and how you like to spend your personal time. Assuming you would make decent money, you probably have some choices -- or would your industry people and your class status be a prescription for how you live? Some jobs do that more than others. Some middle or upper class rituals could be very much the same, or so I would imagine. Although granted, the small talk and the philosophical sayings might be different...
