Because it makes a fair point. Humans are completely out of the evolutionary loop at this point, because people with adaptive mutations aren't any more likely to pump out babies than the rest of the world.
Not just dodgy mutations, but our eternal conflict between scarcity and culture could very well come to a head. It's a damn good movie (like so many other prescient Mike Judge works), because it points out a very real fact - in the developed world, stupider people tend towards larger families, smarter people tend towards small numbers. I think it's still fantastical parable because it takes extraordinary generations to make a serious shift in genetic tendency, but nonetheless, our ability to support ourselves and generate new people has outpaced our consciousness to limit ourselves. In animal populations, this inevitably leads to massive die-back.
To keep up the funny, I can't find a good video of it, but Bill Maher correlated some other fun facts. In the 1930s, the average American ate 6 pounds of cheese a year; today it's 30. At the turn of the century, the average American woman's shoe size was 4; by 1970 it was 7; today it's 9. Add to that, the average height of people of European decent has increased by about a foot over the past 400 years or so. We
are evolving - a segment of humanity is evolving into semi-intelligent livestock with no predators save disease.
