A significant issue for western (Anglo-Saxon) culture is care for the elderly in the next 50 years. Multi-generational living in America is frowned upon. News articles and movies about kids living with parents are framed as a failure. Elderly parents living in multi-generational homes are seen as a burden.

It’s telling that boatloads of money are being invested in elderly care via the gig economy and artificial intelligence because the multi-unit family is now the exception rather than the rule.

In some cultures, a three or four generation family under one roof is seen as a blessing. Family knowledge, heirlooms, and folklore are passed down and kept alive. The grandkids keep the grandparents young and useful. Young at heart grandparents are also excellent baby sitters and companions.
