Finally a voice from the outside.

I lived in China for 5 years. Many appartments had multiple generations in them .

What might come as a shock as single generation family living is the exception not the norm.

It might also solve other problems too.  Child care, elder care, loneliness.  But today many families in the West are to fragmented for this to work.  I'm not saying it's without flaws, but an idea.

And American single family houses tend to be, bigger square footage wise, compared to many houses multigenerational families around the world occupy. 

It is not glamorous or fun option but it is valid alternative to living on the street.
