To incorporate the chart into the model I will only have to make the triangle dualistic in nature and to do so, while also taking into account the triangle's hierarchical nature, I will only have to concern myself with the apex because whatever goes down there will trickle down in an information cascade to the tiers below. So the top tier (philosophy) can be either inclusive ('I') or exclusive ('E') even as it assigns either an 'I' or an 'E' value to each of the other three tiers below it. To allow for all the possible permutations to play out, the apex needs to be given four 'I' and four 'E' values which it can then assign to itself and to the other three remaining tiers. Sixteen permutations are made possible this way:
(Philosophy, Politics, Economic Dimension, Social Dimension) OR (Control Bar, Z-Axis, X-Axis, Y-Axis)
 1. I,I,I,I 5. I,E,I,I 9. E,I,I,I 13. E,E,I,I 2. I,I,I,E 6. I,E,I,E 10. E,I,I,E 14. E,E,I,E 3. I,I,E,I 7. I,E,E,I 11. E,I,E,I 15. E,E,E,I 4. I,I,E,E 8. I,E,E,E 12. E,I,E,E 16. E,E,E,E
Every person has a triangle in Plato's cave as does every group, people, or nation. A triangle's size is determined by the extent of influence the philosophy nested in its apex exercises in the physical world. Smaller triangles are superimposed over larger ones. The world's borders are not delineated by country but by philosophy and they may shift from time to time in a game of triangles.
As a philosophy cascades down a triangle, it manifests in ever more crude forms of expression. At its most crude it manifests as a physical structure. Back in the day people used to build cathedrals, today it's shopping malls: the larger the triangle the more ubiquitous its cathedrals of desires become.
Note that the cave's interior is a desire-driven and therefore an egoism-proper and therefore an exclusiveness-proper environment while its exterior is a desire-free and therefore an altruism-proper and therefore an inclusiveness-proper environment. As a result, inside the cave the 'E' value is a true value while the 'I' is a false value. By the same token, outside the cave the 'I' is the true value while the 'E' is a false one.
Thus expression of the 'I' value inside the cave is but a simulated one, an instance of such principles as the Golden Rule in action. The default expression is that of the 'E' value. But human beings have an intuitive yearning to evolve and to express the true 'I' value, i.e. to step outside of the darkness of the cave and into the bright light of the open expanse. Thus our obsession with religion and spirituality and our interpreting of them in an exoteric light, i.e. as an expression of the false 'I' value. Outside the cave the interpretation becomes esoteric in nature, meaning that of the true 'I' value.
According to Plato, the most important purpose in life should be to look past the veil of illusion and to perceive the true reality, something that can apply to individuals (i.e. on a micro scale) and to communities or nations or indeed the whole world (i.e. on a macro scale) alike. However, it is an effort that is as difficult as it is important as it requires a person to have quenched all the egoistic desires save the one for knowledge. The desire for knowledge will then fuel that person's search for answers to the Big Questions, which most certainly will constantly involve putting cherished beliefs through the wringer. And even then true reality will not dawn unless the notion of past and future is quieted and the now is perceived. It is, however, possible to help the process along by advancing inclusive philosophies, politics, economic policies, and social policies (I,I,I,I). Such endeavor should be in fact the most important thing a nation state could do to justify its existence.
On to the questions:
1. What is the acceptable price tag for your multicultural dream? How many crime and terrorism victims would it take for you to say the price is too high?
It's not a dream but rather a Platonic illusion. What you call multiculturalism cannot be made to work through the manipulation of the physical world because doing so would only highlight existing superficial differences. Your referring to it as multiculturalism attests to this: it implies the bringing together of different cultures. Inside the cave, differences are perceived as a threat to the quenching of egoistic desires. Clashes will ensue. To make multiculturalism work you will have to transform differentness into sameness.
