There is no such thing. What's better for one person will be worse for another. In general, the less developed an area is, the more affordable it is for the working class. However, that comes with the trade off of fewer services, self-reliance by necessity, not much to do, and lower education standards. The US is generally a capitalist hellscape for the lower classes. You have to be very realistic about whether you can afford to live in the nicer cities, and also realistic about the dangers and lower of quality of life if you choose to live in a poor area in an economically stratified city.
