Sure, you're financially better off in the US, if you don't mind your kids going through active-shooter drills at school, getting shot at sometimes by their classmates, yourself being shot at when you're driving to work by someone with road rage, religious and political nuttery all around, and society in general breaking down. You're also totally forgetting the extremely high cost of living in the US, the possibility of medical bankruptcy no matter how much money you make, I could go on and on.
Honestly though, if you actually like living in the US, you should stay there (this goes for anyone). If you're not unhappy there, there's no good reason to leave for a country that's so completely different and unfamiliar, where you're not likely to be happy at all. The reverse seems to be true for your wife, so I recommend divorce so she can go back to a place where she's happy. The two of you seem to be incompatible. I've seen other marriages break up over the partners being unable to agree on where to live or to retire; to me it seems to be one of the most fundamental compatibility factors there is in a relationship, though it's frequently ignored or overlooked.
Also, jobs paying over $350k are not common in America as you seem to think.
