Left/Right Structural Synopsis

A curious structural arrangement of the Left/Right dichotomy, in ideological and philosophical terms not political, is where each begins and where they end. Keep in mind that in both cases you are dealing with the same variables. That is to say that you can give the exact same situation to a person on the Left, and receive a radically different solution to the situation as you would from a person who is ideologically Right. How? Pragmatically there are solutions which work and those which fail, ideology does not come into play. However, because of the general structures employed by each side they function to varying degrees at different points along a timeline.

                Note: For clarification my definitions of left/right are roughly along those outlined by graaaaagh's tripartite breakdown, but lumping them  into broader categories: 

Left is- Left, Progressive and Idealist

Right is- Right, Reactionary and Realist.

In terms of structure:

-The left places emphasis on the collective, in order to benefit the individual. A logical extension of egalitarian ideas, this ideology's final goal IS the individual's benefit, but on the terms of those who defined the collectives. The leftist state passes legislation which benefits a particular group, but their evidence of success is individual. For example, in aggregate, affirmative action has done nothing to benefit those groups it was created to elevate, but there are stories of people properly taking advantage of the system provided (this does not condone the system, but merely observes that people like Sonya Sotomayor played the system to maximize their outcomes).

-The right places emphasis on the individual, in order to benefit the collective, or society. A logical extension of Darwinian ideas, this ideology's final goal is the success of the species, but it simultaneously recognizes that this can be accomplished only by playing into human nature, not trying to manipulate it. A right state passes legislation which allows for the Darwinian experience to flourish on an individual level, but their evidence lies in the successes of society.  For example, the Industrial Revolution saw those capable of better living in the environment of an industrializing society competing, succeeding and failing on an individual basis, with a net benefit to society as human standards of living grew at unprecedented rates.
