The trick to reconciling this, I think, is the Loose Moral Standards. True, the better of a person you are in life the better reward you get in Heaven, but 1) Who's counting? (The FSM? We know how unreliable He is) and 2) Who's keeping everyone in their respective reward areas?
Moral reform is possible in Heaven, so even those who start out at the bottom of the volcano may eventually drink from the Cup of the Caldera. It is said that with a finite amount of matter and an infinite amount of time, every possible combination of that matter must necessarily happen an infinite number of times. Heaven is like this, I think, where the matter isn't so much the matter of Heaven (for Heaven is, of course, infinite), but it's the different levels of Heaven (The FSM is only so creative). Given an eternal afterlife, everyone gets every reward eventually, and always.
Of course, there are other Pastafarians who simply reject the idea of any sort of partitioned Heaven, and believe strictly the original scripture. When anyone dies, they go to heaven, and there is a Beer Volcano and a Stripper Factory. Nothing more, no less.
Every dead body that is not exterminated becomes one them, it gets up and kills. The people it kill get up and kill!
But if I stop bugging you I'll have to go back to arguing with Qwerty about whether beauty is truth and precisely what we both mean by 'purple'
