For some reason it feels like you wrote everything twice. For example...
I’ll also pre-commit to buying at least 200 stools from your baby for $20 each in the first 2 years of its life—assuming (as is likely) that the baby actually ends up being a good donor.
and I will pre-commit to buying at least 300 stools from your baby for 20$ each in the first 2 years of its life—assuming the likely case that the baby actually ends up being a good donor.
...and there were more examples like that.
Good luck, I hope someone takes this generous offer, because it really seems like free money. But you would probably find more people with babies and needing an extra income at some other community.
I think they mention in Economics 101 that there are two major exceptions to this: labor and land.
It’s usually said the other way round (if the price goes up, the supply goes up), and then it’s obvious that the supply of land is more or less constant, and the supply of labor of poor people is “as much as they can” and if you pay them too much they become rich and now they can choose to work less and have more free time.
