This graph is why I don't like in the USA. When my parents got their green-cards after my dad finished his post-doc in California he spoke to all his researcher friends and noticed that in the US it's common for family to move away to other states so they returned back to our country. Since I live in a small country - I see my parents (and my in-laws) almost every week and they help (considerably) with child-care and see their grand-kid a lot more. I wouldn't hold a grudge if they helped less but seeing the joy they have when they're with him probably makes it worth giving up living in the US for them. Family members do live for a year or two abroad at times (for work) but always return.
