Thats fine and dandy and easy for you to say since you speak very intelligently, but the fact of the matter, in todays world, unless you miraculously make it as a rapper or an athlete, ebonics = no job.
Bit a of distance from whether Beats and Apple could be/will be a match made in commerce heaven, but....
I find it ironic that to be in the position of defending a form of music I ceased to like after it passed from Sugarhill Gang and Jazzy Jeff to pick up lots of unsavory themes, and much of which (but not all) I don't personally respect that much or find that much virtue in, but them's the breaks...
First, the "ebonics" label (while coined, I believe, by an African-American teacher) never took off in the community you're implying "speaks it" - so your use of it externally (and derisively) to label that community when it's not used internally has a whiff I know I don't care for.
Second, you act as if everyone who's into rap speaks only in "rap," lacks language education and is unemployable - all of which are demonstrably anything but the situation.
(As in I can enjoy Irish dance routines, without losing the ability to move my arms when I walk. And equally many rap afficianados are quite capable of speaking and writing mainstream business-friendly English.)
On the other hand, it's sadly true that the unemployment rate in most African-American communities has chronically lagged that in others (and we could talk about other social problems as well) - but
ALL of that was true long before Dr. Dre and his cohort were born, so, while these are meaningful, real, serious (and complex, multi-variate) set of problems, with causes in both the effected groups and society as a whole, whatever, the reasons simply don't have their roots in hip-hop culture.
Also many genres of modern music pretty much across social lines are angry, noisy, full of in-group slang and promote highly-arguably offensive attitudes and destructive activities.
Third, "creative spelling" and other "preversions" of "standard English" aren't limited to those in your inferred "ebonics community," but is actually encouraged in some school districts.
With calc apps and keyboards, e.g., whole gens across the nation aren't learning numerical concepts or the fine coordination skills necessary to write cursive - which carries over to other motor and brain activities - which is part of why the US ranks something like 12th in language skills and 26th in math and science.
And I know I'm appalled by the general lack of "basic skillz" and huge gaps in the general fund of all kinds of knowledge in nearly all of the products of modern American education - including among college grads from families with plenty of advantages.
So there's plenty to talk about and work on. But it sez here it ain't 'zactly what you're implyin'...
