I think, you are romanticizing a very painful aspect of life, to which there are no clear answers. As some where later in the thread, your argument is more about assigning virtue to need(because of not enough options).

Another place you mention daughter-in-law caring for the elders. Totally ignoring the sexist nature of that proposition. Also in reality that whole in-laws under the same roof, has its own set of complications. Often resulting in a very unhealthy dynamic. When children also get affected in the politics of the grown ups.

I think, this is a very complicated and painful problem. For that no universally good solution exists. Its a problem worth solving though, anywhere in the world.
