Anathema
Crotchety Olde Man
The people of whom I speak or not necessarily sitting down. Many of them are the Working Poor. Believe me, I don't think middle class whites, used to living a life of luxury, are going to want to trade places with the Have Nots who are barely making it.
I think you might be unpleasantly surprised with how many Caucasians might jyst "sit out" a minority dominated society. In fact, I think an even higher percentage of low income people may choose to do so thsn those of us in the middle class.
So what is the solution? I've heard some evil rumors that are hard to fathom. Some conspiracy theorists have posited that there are Laboratories manufacturing designer pathogens genetically manipulated to attack certain racial characteristics. Of course as these new diseases emerge, they will be classified as idiopathic phenomena of nature and the victims will be blamed for their own demise.
The fix is far easier than your conspiracy theories. It's been commented on by such celebrities as Ben Franklin and Darwin. I believe that Mr Franklin made his preference to solve the problem of the poor by making their lives as difficult as possible. Mr Darwin called it Natural Selection.
