But yes, gentrification can only be racially based, let's focus on a construct rather than something like class and the local labor market.
Do you have any idea what intersectionality is?
Gentrification in and of itself isn't necessarily a bad thing--it
can be good for all parties involved. I live in Logan Square, Chicago so that technically makes me a gentrifier since I'm not Puerto Rican and middle-income. The difference is me and my roommates never once spent money at the gentrified-ass fake Mexican restaurant on our block that yuppies flock to for some reason, i.e. where you spend your dollars matters in the big picture nearly as much as actual housing. Not saying economic development is bad for communities because we all know it's not, but these developments ought to reflect the community and its interests because they were there first. If a hundred middle-class white people move to X neighborhood and buy all their groceries from the supermercado at the end of the block, their clothes from the thrift store a 15-min walk away, and go to the bar down the street that's been there 30 years, the community would--economically speaking; as cultural considerations also come into play--exist as it were before, if not better.
Still, the
main problem is that there's no rent control and people get priced out. Even if families can continue to afford rent, who's to say they can afford to keep buying groceries in their own neighborhood? Not to mention culture which has persisted in communities for decades can get wiped clean in a matter of years at most (I live in Chicago, this is what's happening in Pilsen currently, see also: Humboldt Park, Logan Square, Wicker Park, Bronzeville, etc etc). Of course gentrification doesn't have an inherent racial basis, but labor and class intersect with race thanks to the institution of racism and existence of a de-jure-then-de-facto-but-still-secretly-de-jure racial hierarchy. That's why when we talk about gentrification it always ends up as a conversation about race because most people that live in cheap neighborhoods are black and brown.
