"too frail" to move doesn't make sense - not having enough money does make sense. Look for a job while you have your current one - it is far easier and more successful that way anyway. Country living with a decent lifestyle is for those that have figured out a way to afford it, not for anyone that feels like it.
There are options: just because it isn't what you dream of doing doesn't mean it isn't an option.
There was an interesting thread on reddit about coal towns in (I think) Virginia, and the mindset of people there and the situation they were in. It was stated that there was a large pool of money in the state available to people for retraining (coal to trucking or solar development, etc) and something like less than 25% of the money was even used.
A woman I know got a simple laser cutter and designed a site around doing craft projects with it. In under a year she has thousands of followers and is making thousands a month doing it. I mean, hell, just get you and your friends together and say, "ok, we need to get out of here, lets all live together as cheaply as possible, until we have enough money, then rent some place in a better location, and live there, pooling resources, until we all get better jobs."
There are options, now more than ever with the Internet existing and the mind numbing amount of resources it brings.
people aren't created out of a vacuum and randomly choose a place to live. What if your 70 year old mother is simply too frail to move to a city? What if you desperately need the monthly paycheck and cannot just go months without pay looking for a job because you care for your child? What if you simply do not want your community to rot away because every abled bodied person runs off to the city?
People aren't just amoeba in a lab experiment.
