It really depends on the country. Anecdotally Chinanese girls from deeeeep mainland China are materialistic. They sorta can be since there are so few young girls in China so they can be picky.
Girls from Taiwan, Philippines ,Japan, Vietnam, Thailand are not like that.
Countries have a mixed bag of people. Some people only care about money, some want to make the world a better place, some are only interested in making a living and raising a family. Human behavior doesn't change from country to to country, ethnicity, or religion, or even historical period. The only thing that changes are the outlets available to reach thise goals. Ancient Egyptians, Roman citizens, Arab nomads, Mongolian shepards, Aztec farmers, Appalachian coal miners, and some future Martian terra former all want to make sure their needs are met.
I don't think you can really generalize based off race/location. American culture lends itself to being extremely materialistic, but plenty of people from the US find it disgusting.
It's entitled rich people. It's always entitled rich people. They're the same everywhere.
Sounds like your girlfriend might be studying here with a student visa or born here. Typically those girls come from very rich families and their concern is not "How do I use my daughter to make some money" instead, they are more focused on the child's needs.
When I say DEEP China. I'm talking about girls that is middle class and below in China.
I have friends that had to give a million rmb to her family to marry a girl. And do some fucked up shit during the ceremony, like drink foot water.
