I think the previous answers are underrating how desirable stability and certainty are. They seem to be saying that most people couldn't be happy in a community like Jonas's. I think most people could be, particularly if they don't know anything else.
Think of all the stress that we undergo because of the lack of certainty in our lives. If you're in 9th grade now, you are probably already wondering where you will go to college and what you will do to support yourself. You are wondering how you will be able to have a secure life economically. You are wondering if you will find true love and have a happy marriage. Or at least I did at that age. Now, of course, I have worries -- some are the same, some are different, but they're still there.
Imagine not having any of that. Imagine having someone else determine how your life will be. Imagine knowing that your life will be stable and secure. It would not be all bad by any means, particularly if you don't know you're supposed to be having love and other emotions.
So I don't think the community is that bad. Sure, it's got real problems, but we have to realize that there is something very desirable about what they have as well.
