Isn't the foreign national's status kind of captured at the discretion of the employer?

It sounds like a larger power asymmetry and as an employer, you want that as large as possible.

I mean it also increases stress on both ends, which affects executive function so the parties become handicapped by the relationship, but that's apparently less valuable than the large power differentials to many.

I wonder if there's quantitative studies of firms performances with respect to this. If the theory is right, it's long term one of the more disadvantageous strategies. (Using Apple as N=1 doesn't cut it as a study here)
