well...you can always take in consideration the growing factor.... one thing that dolcett stories don't take in consideration is the enormous period of time a spitmuffin require to grow...in his stories somethin like 16+ years.... it's an infinity to wait.... remember that movie with r. williams?.... where he had that genetic defect... that cause an accelerated growth of 4 time faster.... of course it's fiction (a growth like this would cause devastating deformations in the subject).... but dolcett is fiction too.... and let's say this defect don't cause any physical damage to the meat-maids...in fact it's more like an evolutionary step....women just grow 4 times faster (and to stay on the topic, men of course grow at normal paste).... so in mere 4 years you have a fully mature and fertile female subject...and plus their intellectual capacity will be more reduced since growing so fast don't give them enough time to form a complete personality....and of course making them more gullible and credulous... (who wants a cow too smart afterall lol).... and probably also, from an evolutionary point, there would be more men then women since a male can impregnate a large number of women in a short period of time (and making men live longer would garantee a more solid chance for procreation....)...sry if i didn't talk about math too much...i'm kinda suck at it...but hey....studies shows that it takes (on average) about 24 hours for the man's body to produce enough semen after ejaculation for another ejaculation....so if he fulfill his quota of impregnating on gal a day...that would make 365 gals a year.... so a ratio men : women like 1:300 would be sustainable (i didn't put 365, because a men need some holidays, festivities, illness day... etc.).... and with such a huge number of women you would have an enourmous working power at cheap price...especially in agriculture....that of course would sustain the alimentary needs of the whole population... they would not be suitable for industry of course... put a girl to operate a machine... you know it's gonna be a disaster XDXDXD (ok that was probably sexist....but who cares lol).... probably givin' them simple jobs because of their low IQ, like harvesting crop and wheat, farming (in other words milking themselves XD), household...but of course all under strick men supervision.... and also diet must be taken in consideration...since allowing women to eat meat would drastically reduce the meat supplies...so their primary food resourse should probably be based on vegeterianism... and last main point there should be a reason why humans choose cannibalism over eating animals....an there could be plenty of reasons.... viruses, wars, peta bullcrap, space colonies (like a disaster that causes on that colony planet to remain as only living creature the human survivors....and they had to survive somehow lol....ok...now i'm just digressin)...

sry if i went off topic a little....but i wanted to take somehow a more large perspective on that kind of society...
and sry for my broken english too...
cheers
