Although some states in the United States stipulate that children must support their parents when their parents are incapacitated, in real life, most incapacitated elderly people are taken care of by their wives. If both of them lose their mobility, or one of their wives leaves first, then the elderly will choose to enter the nursing home.
American children may visit their parents regularly, but they will not pay their parents' living expenses and medical expenses, and in general, the court does not support parents to ask their children for alimony. This situation is determined by western culture. However, compared with China, American parents invest less in their children. First of all, it must be affirmed that both Chinese and American parents love their children, which is beyond doubt. American parents rarely help their children when they grow up, and rarely help them take care of their children, let alone help them buy a house.
Of course, the children of local tyrants will get more care from their parents, but some people will be "swept out of the house" when they grow up even if they are born in rich families. As for the children of ordinary families, they will live independently as adults. Although young Americans can't rely too much on their parents, they have no obligation to support the elderly. On the streets of the United States, you can often see some old people "shopping" alone, and there are few young people around.
