The Mean Yellow Meme?

Somewhere in the month of march a young person from India said something very strange to me: "What else to expect from those people; they are really low cast, they think differently. Most people of that family think like that. It is passed from generation to generation." I protested of course, because I think all people deserve to be treated equally, and generalisations don't work. But moments later it struck me that the cast system was nothing more than spiral dynamics in a different era. And ... this era is everywhere, also today. Replace the words "low cast" by "different social class" and your mother in law could have said this.

So we have a beautiful example of spiral dynamics, solidified in a society. And that solidification is of course different from the intentions of the proponenets of SD(i). Because the cast system is not a spiral anymore, but by stretching it has become a system of concentric rings.

Todays philosophers and sociologists should however be very aware that spirals are easily stretched, and that the connections between the layers can break. Even a perfect implementation will after some time change shape. The Weimar republic became a national socialist state only 70 years ago. The best intentions of Lenin and Trotsky became the horror of Stalin, and I'm sure, also Pol Pot was implementing an ideal society by the most attrocious means.

Maybe in a not so far away past, the cast system was an invention of progressive philosophers in India. Only the Brahman cast, on the top of the hierarchy, combined with the right political powers, might have thrown the spirals in a bath of concrete, to spell the fate of paria onto generation after generation.

Could this be the mean side of the yellow meme?
And if so, how can we prevent this to happen, if SDi (remember the Strategic Defense Initiative) ever gets on the political agenda of the nations of this world?
