I remembered something
very important about it. One should never forger because when it is about the GDP per capita, it also matters
which place (city, town, village) in the country you're talking about!!!
For example, some little towns in a very rich (per capita) country (like Finland, Norway, Sweden, etc.) have got less (GDP per capita) than some cities in countries like India, China, Mexico, etc.
Let's see Shanghai, taken alone, as an example. According to
https://en.wikipedia.org/wiki/List_of_Chinese_administrative_divisions_by_GDP_per_capita, in 2022 it (Shanghai, China) had GDP per capita of USD 26747. More than the average GDP per capita of some countries in Europe (like Serbia, Belarus and even the EU's Bulgaria.) Shanghai's level is around the average one of Malaysia (USD 26300). (All data seen in
https://www.cia.gov/the-world-factbook/field/real-gdp-per-capita/country-comparison.) But if you live in China's Guizhou province, where the GDP per capita was USD 7779, oh, it's really another story. This GDP per capita is around the one of Laos (USD 7800) or Venezuela (USD 7704)...
I bet that it also matters which district of Shanghai we're taking into consideration, when we are going to make the conclusions about this kind of matter.
And, at the end, as my friend said
the wealth of a country is a different story from the wealth of the ppl of it.
and I'd like to use it to say "the wealth of a city is a different story from the wealth of the people of it", i. e. even in (not poor) cities like Shanghai, Beijing, Chongqing, Guangzhou, etc., there were and there will be poor people and very poor people.
If you want to learn about it (the wealth, money, rich and poor) more, take a time to see a very important index -- the Gini index (which helps you better to know the matters related to the GDPs per capita, especially).
