The Ultimate Life Change

'Trading Spouses' broadcasting by Fox TV has recently broadcasted on Korea Cable TV. Families exchange one of their spouses, Dad or Mom has to live in completely different family for a week. Then, the spouse will have to decide where 50,000 dollars to be spent. The result sometimes come out to be good, or sometimes not. I think it's one of the most interesting programs. As far as I know, there's no such a program in Korea. If I were a producer, I would make that sort of programs. People will notice how much it is different to live in other families. They may appreciate their spouses and other family members, or they may find a strong relationship with other family by having a chance to live together.
The program has at least two benefits. It's fun, and provides viewers with a chance to tak a look into other family's life. Why don't Korea TV stations make similar program just like this?
