In one part of Brave New World they bring up that they tried to do more automation, but people got restless without the drudgery. In another part, they bring up that they tried to have a society with only Alphas, but they didn't want to do the drudgery.
I wonder why they never tried combining both?
I thought, something like a medication helping the women develop the baby in 30 days, but seriously damages the host in a couple of days, so the fetus gets transferred from host to host. Some die, but the evil rich don't care. Your idea could also work though.
I realize that this is totally the wrong corner of the internet to post this but I guess today I'll just go with it.
As a premise for science fiction, it sounds like it might be interesting.
