And if you lived in China, you as grandparents would be living with the children and taking care of the grandchild (just one, most likely) in a tiny little house or apartment. You wouldn’t be living an American lifestyle with a car and your own home and perhaps a gym membership or nice club. You’d be doing the grocery shopping and making the meals while your child worked and your grandchild went to school.
Is that the kind of support you expect your children to provide to you, a room in their home and you’d be the housekeeper and cook?
