Jeff said in some interview last season that people take into account how much a person "needs" to win when they vote. Poor people fare better.
I'm thinking that the casting director threw in a couple rich people just to see how others' would react to that aspect of them. Does money really influence who you vote for?
The flip side is that it's cool to say "I was on the tribe with *famous person*!". They may keep them around because of the fame.
but not the money.
Another interesting twist, actually.
