Justice Department Seeks Ebonics Experts
In addition to helping decipher their Lil Wayne albums, the Justice Department is seeking Ebonics experts to help monitor, translate and transcribe wire tapped conversations. The DEA wants to fill nine full time positions. From the article: "A maximum of nine Ebonics experts will work with the Drug Enforcement Administration’s Atlanta field division, where the linguists, after obtaining a 'DEA Sensitive' security clearance, will help investigators decipher the results of 'telephonic monitoring of court ordered nonconsensual intercepts, consensual listening devices, and other media.'”
To answer your question about age grading, you have to look at a population at more than one point in time. In cases where this has been done (e.g. speakers of central American Spanish), what we find is that young adults have the highest percentage of the incoming feature (higher than both children and older adults). As those same young adults get older, their use of the incoming feature does decline some, but not down to the levels of the previous generation. The 40-year-olds today have a higher percentage of the incoming variant than the 40-year-olds twenty years ago.
Variants in speech can serve as social markers which you use to identify yourself as a member of a group. As a guess, I imagine that the slight decline in use of the incoming variant as you get older has less to do with "learning standard English better", and more to do with it not being quite as important to sound cool as you get older. As a 40-year-old, you probably still wear clothes which identify you as a member of a certain group, but you probably don't dress in quite as trendy a way as you did when you were 20.
I saw this poster in 1999 on a fellow's cubical wall at a place where the company I worked for was putting in a software system, in Rhode Island. The blog where the picture is hosted from provides the text below the picture. It was commissioned by The National Head Start Association. For those that it matters to, the person who put up the poster was black. It was no surprise when I saw it for the first time, as I found previously that he placed a lot of emphasis on being able to communicate effectively with those around him.
Your politically correct stance does not help people. In order to overcome prejudices it is best to focus on our similarities with others rather than on our differences. Once that is done, the differences don't matter as much. We cannot focus on anything if we cannot communicate. It doesn't help communication when one community works so hard on creating a wholly new dialect, if not language, just so that they can be more different.

or that maybe one ought to not make such a big fucking deal of the fact that a bunch of underprivileged people in this country speak a dialect different than yours.
If they don't speak the same language, they can't get a decent job. Then, they stay poor, and liberal whiners claim that these people are "underprivileged".
Sorry, but you can't have it both ways. If you want to speak a different language from the de facto language of economy in your nation, then you can't complain when you don't get to take part in the economy and raise yourself out of poverty. The tools are all there: remember, public education is free in this country (in SAE of course).
The reason it's a "big deal" is because the AAVE-speakers (and their liberal apologists) are always complaining about being "marginalized", "underprivileged", etc. Well, they're doing it to themselves. And yes, AAVE speakers do it willfully. I've been around many black people who could switch automatically between "white English" and jive depending on who they were talking to. Again, public education is free in this country, and it's done in SAE.
I grew up in the South, where people speak their own dialect. Speaking with a Southern accent is NOT a route to success in anywhere outside the South (or in many places inside it), as most Southerners will tell you. As someone more interested in being successful rather than "preserving" some dialect, I learned to speak proper SAE growing up, and never bothered with any regional accents. The way people spoke on national TV was the way I learned to speak, and made sure I spoke. I never complained about this.
