I think that in the great debate regarding the various discriminations of sex and race and all the other things, eventually, the world will resolve all these issues into the simple ongoing battle between rich and poor...as this has always been the only real human discrimination that amounts to anything...and we are not half there yet to working out what to do about it. Eventually, the poor will show us the way. The rich have always depended upon the poor to make a profit, whereas the poor have no dependence upon the rich ever or at all. if there is to be a revolution, and I think there will be, it will not be launched by the well to do...and the well to do, folk just like you and me, won't like it at all.
