Paranoia sez "Hi!". Well training is random rather than identical, but you do have your six pack of clones and making a new character is under 5 minutes (may vary by edition a bit but not too much).
Pretty much just this. Meatgrinders aren't really set up as backstory generators and aren't universally applicable. Life path character generation is a backstory generator (and I'd still pay real money for reverse life path generators that work backwards from a completed character for certain game systems & settings).
