I don't know if this has been mentioned yet or not, but here's a podcast of THE MARCHING MORONS

Just listened to MORONS today. Kornbluth's satire is even darker and rawer that with BAG.
Also, everyone should go check out Paolo Bachigalupi's story PUMP 6 - it's like both of these but pushing even more raunchy and dark buttons.
