Maybe you can read the book @lo while you're thinking.
The reality is that white people broadly just marry whoever they want, they don't have to worry about generational wealth, and as a majority group, they feel more like a default state than a community.
Other races may think about community more, but a lot of that is often tied up with specific national cultures or religion, it isn't a given.
White people think about community and wealth more than you think. Why you think they fight against Universal Healthcare, free college, public transportation, gun control, militarized policing and etc.
A lot of politics that White people have is about maintaining patriarchal control over their family. They know ethnic groups such as Nigerians and Korean Americans might be able to pay for college out right, but they know damn sure we can't. They got about 4 cars in their drive away, of course they don't want good and efficient public transportation, they don't want "undesirables" to be able to even get to their community. In Europe, it's prohibitive to even have a car. In America, they use highways to segregate.
A lot of things that America doesn't have is because White people have been able to pay for it outright since the 1950s. They got great great grandma and great grandma money due to slave labor. Their grandparents buying them houses and shit when the baby comes. Their parents paying for their apartments. And rich White people don't really need the government to do anything besides ensure their property rights, so they definitely don't want the government doing anything for anybody.
Black Americans mistake community and care by like, how much they see their grandma and if they know all their cousins for some reason. White people think of community and care by how much they can kill off and oppress another group and extract resources from them. How much they can prevent another group from having something.
White people just used Asian people to destroy affirmative action, not legacy admissions for a reason.
For White people, community is a militarized force for the benefit of their kind. It's not just people living together. It's based on competition. White Americans have a colonial history, they aren't lovey dovey people that just wanna go to church on Sunday and go to Big Momma house for dinner.
