I don't think available goods and resources was as bad as this thread was making it out to be
I had two great grandmothers that lost the majority of their children as babies/toddlers.
I think a lot of people are not accounting for the costs of risks during that time. If everything went well, the rain was on time, no other nations attacked, no one fell ill, there were no birthing complications, then life was okay. But nature usually throws a few curveballs.
The sole question is can you on 100 dollars a month today live in a manner similar to what the average person in the 20s did
The empirical questions are what does 100 a month buy you today and what was the average lifestyle of a person in the 20s in terms of how much would it cost to buy that lifestyle today
Questions of how we got feminnism and better medicine since then is irrelevant and trying to distort a simple empirical analysis into a political one
The resource cost and availability that existed in 1920 were because of non-empirical decisions like politics and societies adaptations to new technologies. It's like you're taking a still frame of an avalanche and looking for a flat spot to build a foundation.
But half the population lived in urban areas and only half of those people had electricity. So 50:50 you end up on Schrute Farms with no electricity and an outhouse.
Not even mentioning race here.
My read of the parent’s comment is that you aren’t paying for land.
You don’t need store bought fertilizer. I had a garden for a few years and avoided manufactured fertilizer for most of it. At an industrial scale, sure, it is needed, but not at an individual garden level.
No transportation needed other than your own two feet or what you can build. It’s not like you need to go into work every day.
You don’t need to buy animals for food if you can hunt and trap.
I’m not suggesting I agree with the $100/month limit, but things on your list are considered luxuries to the plan. Remember, you’re shooting for “QOL of someone that lived in the American West a hundred years ago” which wasn’t all that great.
