Well, the Amish already do this... when their kids turn 18, they send to live in New York for a year or two, to see if they like it there or would rather come back home. I believe a bit over half go back home eventually.

I don't know if they'd want to televise their experience, though.

Do they really? I had no idea..And I never saw an Amish when I lived there -if you mean NYC...?

The Mennonites send the boys out only, not the girls. The young Mennonite girls had too much fun and tended to stay more than the boys did.
There is also some sexual selection going on. If you want to have kids, a Mennonite community is a much better place to raise them. You can support a family easier than in a city.
