I predict that lots of American folks will want to do those low-skilled, poorly-paying jobs when they need to fill their tummy and have no other option. This creates a conflict, and our government has already picked sides on the issue: NOT OURS.
Also, Affirmative Action: When times get real tough the populace will have no more patience for quotas and racial set-asides. Would you be willing to allow a lesser-qualified person get the job you want, nay, NEED? Would you willingly allow your kids to starve due to the color of their skin? I wouldn't.
I bring up those two points because I see a simmering anger in the populace right now regarding these topics, and would assume it would get worse with our coming hard times.
Along with that comes distrust of people in general. Engage when possible, do not engage when not possible. I was active duty. Violence will bubble up from the untrained. Tensions are high, so be aware.
It was wildly successful. We now have a POTUS that is living proof that skin color trumps skill/ability every time.
J.J., Al and Louie are out of a job. Blacks have achieved compete equality. Everyone IS equal. No need for the government to stack the deck any longer.
