They're too smart for that.
Low income people in Brooklyn, and elsewhere, have managed just fine for over a century. They get many of the things they need from the shops there which are owned and operated by people who have a stake in the community, and are often low income or at best middle class themselves. Thats how a community works. And the capital that isn't siphoned off to Albany or Washington stays in Brooklyn.
Walmart would siphon off more capital and send it Bentonville and Bejing, flooding the area with cheap trinkets and garbage products in the process, killing generations of neighborhood small businesses. In exchange, a few people get dead end jobs. Oh, and some grease flows to a few squeaky wheels.
This is inconsistent with-- in fact, directly opposed to -- conservative values. Nobody who supports this process has any conservative credibility. You are clearly on the wrong site.
