Nonsense.... I lived on under 10k/year for close to a decade in rural Oregon- a while enough ago that that would be about $14k/year now adjusted for inflation. I had a decent 2 bedroom apartment, two older but reliable cars I got for nearly free at auto auctions and a fast motorcycle, and cooked my own meals 3x/day from top quality local farmers market ingredients. I'm talking REALLY good food, the best quality fresh…
I think if you look you'll find that housing costs have rapidly outpaced inflation, even in rural Oregon. Studio flats in La Grande are approaching a thousand dollars a month. I believe what you're saying is true, but I don't think the experiment could be replicated today.
However, there are places more affordable than Oregon... I recently looked at home prices in the Mobile, AL area and it looks like you can buy a livable 3 bedroom home for ~$60k there- that could be about $400/mo for a mortgage.
If one has the skills and knowledge to do so, you can still live very cheap on a boat almost anywhere- I know a lot of people with incomes in this range living on well maintained ~30 foot sailboats, even in the SF Bay area.
A lot of what I'm talking about is substituting skills and free time for income. If you are good at DIY stuff, cooking, etc. you can live better for cheap. I only have those skills because I grew up upper middle class, and had parents that taught them to me- and I was in boy scouts, etc. You also have to have a lot of free time- if you're making $14k/year part time with no kids, it's totally different than if you're working full time and have kids- although the minimum deduction and poverty line will be higher with kids.
I have friends that grew up poor with absent parents, and their lives are much more expensive than mine in many ways- they can't maintain an older car so they have to buy a newer one, they can't cook so they eat out more, etc.
