It's wouldn't be the first time I read too much into something. But, I really think those things, along with the stuff Mongoose talked about are there. Zemeckis clearly has a political agenda in that movie that he is pushing. And, to go deeper, what I think he is really pushing is Gerald Dworkin's concept that success is purely a result of winning the genetic/social lottery and that a world like ours, which is run by intelligent people, who have no right to take pride in that success because it was just luck of the draw and are, therefore, obligated to help those who did not have the same luck.
