Not really. Many elderly people living alone are left to live alone voluntarily, but of course some of them are due to the unfiliality of their children. The question cannot be generalized.
Thanks to the rapid development of cities in modern society, many young people leave their hometowns to work outside their homes in search of better prospects. Once they have stabilized their jobs in the outside city, then the next step of getting married, having children and settling down is mostly in that city too. Sons and daughters settled in the big city outside, they remembered the old parents are still at home, want to take them over to the big city to live to fulfill their filial piety, but many old people are not willing. There are two reasons for this. First, the old people do not want to go to the big city life, said the big city fast-paced, polluted, not good for the body, and the big city does not have their circle of friends, a person is very lonely. The second is that they do not want to disturb their children's lives. With the development of modern family thinking, many elderly people also know that they have to leave a little space for their children's families, and they believe that they are still healthy and do not need the care of their children.
Nowadays, the main force that makes up a family is mostly an only child. If both parents are able-bodied, there are four elderly people in a family, and there are children to take care of, which means two people need to take care of at least five people's lives, and both couples have busy work and socializing schedules, so they really don't have enough to do. Many young couples take over the elderly and ask them to bring up their children for them. The old people may not be willing, but in the way is the children's request also agreed, and from then on, repeat the year when the birth of the children's journey. I don't think this is what is called filial piety.
While many people say that the children of elderly people living alone are unfilial, not all of them are actually unfilial for this reason. Behind the old people living alone, there may be hidden behind a family's unknown sorrow and helplessness, their children empty filial piety but can not be accompanied by their side. Modern fast-paced society has indeed caused the existence of many elderly people living alone, but their children are not unfilial, perhaps they miss their parents every day, insisting on giving their parents a phone call every month to play the cost of living. Although living alone, but the elderly may be happy it!
