2. Are you assuming all or most black people speak this way and/or can't speak 'properly' in proper circumstances? Do you draw the same conclusions for the vernacular of (poor) southern whites?

In the recent past, not having a real education and not wearing a suit everyday severely limited your economic opportunity. Entrepreneurship in the form of "hacker culture" changed that. I think the same can happen with entrepreneurship in the form of "black culture" or any culture.
Please question assumptions, second-guess terms like hoodlum not to be politically correct but to be accurate, and know history explains a lot about why society is how it is, anthropology does too.
