I specifically cite transportation costs in my prior comment. Housing is also cheap if you don't live in (expensive) cities. There's an abundance of housing in the suburbs and if you're willing to share a place with others (like everybody seems to take for granted in the city) it's insanely cheap.
Education and health are interesting beasts. On the one hand technology has brought the cost of education to near zero through remote learning and internet courses. There's more knowledge available at a person's fingertips than at any point in history and the cost is cheaper than ever. The cost of a formal higher education has gone up but I don't think that's driven by technology. It's from the availability of "easy money" for student loans. Healthcare (in the USA) is uniformly fucked and needs to be scrapped and rebuilt though government programs like Medicaid do cover the people your describe (poverty line).
The increasing polarization of the economy is also spatial: the remaining good jobs are congregating in fewer and fewer metropolises where the cost of living is skyrocketing.
