Sounds like a recipe for divorce. I'm puzzled about the benefit to the nation of a bunch of people who hate their lives, each other, and their children!
I know lots of families with six or more children, and I don't think any of them would want to be involved with this kind of thing. It's not American.
As I said in a comment above, a society where the citizens don't voluntarily have children is doomed by its own dysfunction. Tough cookies for Germany, and tough for the U.S. if our birthrate falls below replacement level.

Actually, what I am talking about is a lack of non-child-oriented adult entertainment. If daddy works a dull job from 9 to 5 on weekdays, he looks forward to any time off with his family. In practice, his work hours might be even shorter, since his having and raising children is the real purpose of such a city. Daddy is at work mostly to get him out of the way during the day.
It's harder on mommy, because many women don't see the value in being a housewife and raising their children, very hard work by all accounts. That is why I suggested home-based businesses for women. It gives them an outlet for their creativity, but doesn't exhaust them as much as work outside the home. The energy is for the children, and far more than just two per family.
A family with six children needs at least one parent in full time labor raising them for at least a decade, then half-time until the youngest is reasonably independent. Even so, the older children also have to be mutually supportive of the younger children to help out. And friendly neighbors with kids are also very helpful.
Adult entertainment would still be child oriented. Since their city is geared towards children, there would be plenty of organized activities needing adult supervision, from sports teams, scouting, religious activities, etc. Just an absence of bars, brothels, drugs, gambling, and other wastes of energy. A strong moral base from religious leaders is a big plus, as is some degree of sexual inhibition.
Early on, on the subject, I even mentioned a particular design of housing that has been experimentally determined to be conducive to having and raising children for maximum safety, socialization and parental supervision. A grouping of six or eight homes, each with a breeding couple and their kids, with small private backyards and a large communal backyard.
Such a city would be a great place to grow up. And while parents would find parenting a lot easier than usual, they would find *avoiding* parenting by doing other things to be difficult.
This was the circumstances in the US just after WWII. It was not intolerable to the people who lived through it. And by taking that model, and making it somewhat better, more enjoyable, even more conducive to having children, a nation might boost its birthrate from 1.4 to 2.6, well on the road to recovery and demographic balance.
But it is artificial, and difficult to bring about anywhere, be it the US or Russia or Japan. Its creation and maintenance would take considerable effort, money, and determination by any government.
But it is that important.
