what does buying power mean? like, you're able to buy some house on your not 1% salary in your rural area, and a person on a 1% salary in nyc/sf could not buy an equivalently nice house?

"buying power. the ability to purchase goods and services" (https://www.dictionary.com/browse/buying-power)

So yes. With a lower salary in a specific area, I can probably buy the same goods and services as someone with a higher salary in a different area.
