We are barely getting by as it is.
The poor don't have the luxury of buying new fuel efficient, or electric cars. Our roads are not safe for motorcycles 365 days out of the year. They buy what will get them to work and back hopefully, at a price that won't put them further into debt.
My biggest fear with Global Warming is they make the poor pay for it in sneaky ways.
When smog checks were required in CA, they made it sound like the low income wouldn't be hit hard financially. It didn't turn out that way though. If your vechicle doesn't pass increasing harder smog tests every two years; you end up paying a lot. (I can work on my own vechicles, but thinking about buying a smoke machine because they are now failing for tiny holes where hydrocarbons might escape.)
