And I think the jury is out on “fresh produce” being the key differentiator. It’s hard to find real science that backs that theory up.
I don't know if redlining is the only reason for this gap, or even one of the most important, but it's obviously a part of the story. If you're going to make generalizations about entire cultures this way, I think the onus is on you to engage with the history, even if only to say why you think it's not playing a part here.
Why does "de facto redlining obviously lives on"? How do you know that the areas with less investment in the west side of Chicago suffer race-based discrimination in investment (i.e. "redlining") as opposed to data-based, rational investment decisions?
You can raise the standard of living in the redlined neighborhoods, and that does happen at the margins, but it happens slowly and only when economic conditions across the city are good.
So no, it's not the case that Whole Foods or Pete's is just going to spontaneously site a new store in K-town. They're not avoiding that area because they're racist, but they are avoiding it because of racism.
Regardless, it is not "de facto" redlining, as redlining is race-based discrimination in investment, and that is not what is happening now. If you are criticizing rational, data-based, non-discriminatory investment, then you should not caracterize it as redlining, as the defining characteristic of redlining (i.e. race-based discrimination) is lacking in the current situation.
Redlining is a huge big deal; despite ending in the early 1970s, it literally defines the neighborhood boundaries across much of Chicagoland in 2021. And grocery stores are scarce in redlined neighborhoods, but not as much in working class Mexican neighborhoods.
Or look at a place like south-suburban Olympia Fields, which is majority Black but wasn't redlined (presumably, it's where a lot of upwardly-mobile families locked into Lawndale and Englewood fled to). Plenty of grocery options.
Do you really think redlining has nothing at all to do with this? That seems like an extraordinary claim.
