Dystopian YA as Seen by The New Yorker

Hello, premature readers.  From time to time in the next three weeks, I thought I might pose a few questions to maintain the manic anticipation of re-reading.  Sometimes it may be a simple poll, sometimes it may be a bit more though provoking.  Today I read an interesting article in The New Yorker called Fresh Hell by Laura Miller about YA dystopian literature and its general popularity.  Putting her theories aside (although the whole article is tres fascinating) I felt compelled to pull this particular bit out:  Ms. Miller writes, "Given that the winning tribute’s district is 'showered with prizes, largely consisting of food,' why isn’t it the poorer, hungrier districts that pool their resources to train Career Tributes, instead of the wealthier ones? And the practice of carrying off a population’s innocent children and commanding their parents to watch them be slaughtered for entertainment—wouldn’t that do more to provoke a rebellion than to head one off?"

This is delicious brain candy, and questions I have yet to hear discussions about.  So, readers, why do you think the citizens of Panem submit to the oppression of the Hunger Games rather than rising up against it (at least for now)?  And why do you think the poorer districts don't train up their tributes?  Look at that wide open comment space, just waiting for your ideas.
