Recently, the LA city council voted to ban for one year the opening of new fast food restaurants in South Central Los Angeles (which, by the way, we're not supposed to call South Central anymore, due to the unfortunate events of April 1992 -- it's just South Los Angeles now, officially speaking).
Interestingly, the recent proliferation of chain fast-food restaurants and retail outlets in South-Central LA is actually the solution to an older problem.
As you'll recall, South Central LA witnessed vicious racial pogroms in April 1992 against immigrant (typically Korean) entrepreneurs operating within the black community. Korean shopkeepers tended to treat black customers brusquely and would seldom hire and almost never promote local blacks.
Since then, corporate America, often in partnership with black entrepreneurs like Magic Johnson, has greatly expanded the number of chain outlets in South Central. These are more willing to employ local residents than immigrant mom-and-pop establishments, and promote them too.
For example, the Florence-Normandie neighborhood where the 1992 riot broke out now has a quite decent chain-run supermarket with a first rate fresh produce section.
In general, the Stuff White People Like coterie sees immigrant-dominated retail streets as "vibrant" and chain-dominated retail streets as "boring," but the latter are better for African-Americans looking for jobs.
On the other hand, Hispanics are slowly pushing blacks out of South Central, so a lot of businesses tip to all Hispanic employees. Once you reach a certain percentage of Spanish-only employees, you have practical reasons to start demanding that new employees all speak at least Spanish. And there are virtually no bilingual African-Americans in LA. (Among the 900 black LAPD officers, I was told on good authority in 2001 that only four spoke Spanish -- and LA cops have plenty of career reasons to learn Spanish.)
So, what's different about this is that it's happening in a poor neighborhood, where fast food restaurants have typically been welcome since they provide jobs to poor people. I'm just speculating, but perhaps what has happened in South Central is that black politicians in LA have turned against fast food outlets because so many tipped to workforces that are all Hispanic, because once you have a certain fraction of Spanish-only employees, it makes sense to get rid of all your English-only employees. And African-Americans in LA are almost never bilingual.
The Latino employees are frequently illegal immigrants who don't vote, so the black politicians' electoral base doesn't benefit as much from fast food employment anymore.
In general, black politicians in LA represent districts where most of the voters are black but most of the residents and workers are Latino. This can make for some unusual policies.
