okay, I'll explain why a utopia can't last beyond the first generation
DEFINITIONS
content:  indifferent
In a utopia, it's people MUST be happy, or else it is simply a perfect society.  But to be happy, you need something to compare it to.  you have a good day, you need a bad day, or else it's just a normal day.  You can't say that you have a lot of money, if it's the same amount of money that you've had all your life.  If you've never had a bad day, or a bad experience for that matter, how can you be happy?  You may be the pinnacle of perfection, but not happy.  Simply content.  The first generation (assuming they were imported from the real world, and not raised from day one in the utopia)  will have had real experiences, good and bad.  They will be able to compare and contrast the experiences and be giddy with pleasure at this heavenly place.  But their kids.  Will not have had these real experiences, and therefor, not be able to compare and contrast.
