No. I think humanity should aim for absolutely every single human in every country in every single region, urban or rural could have a level of life quality comparable to what's consider middle-high income level in USA/Europe.
If we cannot achieve that we'd better give up as an intelligent species and leave room for que squids to try.
I said in other comment. I'm not in the US, I'm in europe we have one of the best train networks of the world. Public transport is funded by the government so is cheaper, even completely free in some cases.
People living in rural areas still chose cars while they have the free will to do so.
If as a species we cannot find the way to make that work there's no incentive for us to keep trying. Luckily I'm sure it's possible, that people say it's not just because propaganda (as I said mostly because the voting split rural/urban). We have achieve harder things as a species. Surely we can have people in rural areas still using cars (electric cars for instance) without dooming humankind to extinction.
