Not even close to true. It did trickle down and there is tons of evidence to back this up. The African American middle class has been growing by leaps and bounds since the 80s. The real issue (IMHO) is that African Americans are polorized economically amounst themselves, but this has more to do with teenage pregnancies than anything else. Of course you won't hear Al or Jesse pointingthis out because it's more profitable to whine about how whitey is repressing them.
You have attempted to introduce logic (or at least common sense) into an Al Sharpton Thread. You will be punished.
There is no way any amount of logic or common sense can over come hoodoo-voodoo. It is clear from this potent phrase-making that our next POTUS will be Al Sharpton. Deal with it.
Other candidates can but dream that they could do that old hoodoo-voodoo that he do so well.
