My wife is American and I'm Bangladeshi, and we definitely see the differences you're talking about in our relationships with our families. Especially because we have crazy work/commute schedules and also a toddler, so we end up leaning heavily on our mothers for childcare.

I don't think I agree with your conclusion about "closer family ties." My mother in law is definitely very transactional, while my mother isn't, but my mother will also build up resentment when we exceed her unstated boundaries that will manifest into a fight months later.

Obviously a lot of that is just the particular personalities involved, but I would not be surprised if there was a general tendency for Americans to negotiate more up-front to avoid conflict later.

I think the cultural difference comes particularly to a head in the Sheryl Sandberg example. Let's face it--the typical Indian/Bangladeshi solution to negotiating chores 50:50 with your spouse is for the woman to do much more of the domestic work and sacrifice her career for her husband's. That's common everywhere, of course, but I think it's a particularly difficult problem to solve if you look down on calculating inter-spousal debt.
