Why would mass production be opposed by mass consumption? Does not the one lead to the other? I would expect that it would be more some for of "lack of production"... Actually, I would expect it to be pretty close to "perfection". We would oppose their numbers with our elites. Refinement is a bot off from my prediction of invention. Same family but the species is just a touch off. My theory still holds however, they keep perfecting things which leaves us stifled in the development theatre by opposing that. I guess, if we are lucky, refinement might be opposed by inspiration, which should collaborate well with awareness. It is a little awkward to have two things doing much the same there, but they collude, awareness increasing the scope and complexity that inspiration can entail, so it would be less of a loss and more of a specialisation. I mean, some level of "make lots of stuff" and "get new designs" is a very very obvious route for industry to take. They would pretty much need to be messing with us to switch to something like chemicals or communication. They would be applicable, but not really iconic...
To put it another way:
Freedom: do what you want. Tyranny: do as you're told.
Refinement: endlessly repeat, better each time. Decay: become worse due to progression of inherent instability. Inspiration: become better once through a single event. Erosion: endlessly repeat, worse each time.
Mass production: create many, all alike. Mass consumption: absorb all. Trial and Error: create many, all different(A.K.A. refinement... A.K.A. Evolution...). Perfection: Create few, all alike.
Tyranny and Freedom are both bad. Taken to extremes both will lead to ruin. I do not think that the opposites will be worse than one another deliberately. Also, an opposite is not completely different. The opposite of 1 is -1, -2 would be more opposed to it but would not be an ideal counterpart. They are likely to change one element rather than all. Fidderent means to the same purpose. Freedom and Tyranny both orchestrating the actions of the populace, one towards absolute order and the other absolute chaos. A more fitting absolute opposition to freedom would be death or confinement, to do nothing against your will. Tyranny and freedom both dictate action...
So I think that decay and mass consumption are not good assumptions based on the idea that they will be taking refinement and mass production. I also feel that eternal and sustenance are very similar, but sustenance is more of an attack to their bottom line, with it being opposed by something like suppression, hunger, or revival, none of which work to feed the sustained needs of mass production or refinement which are both hungry for materials. Perfection to awareness are both trying to... not enough time... is not trying to take the cap out of refinement, which rather denies the existence of perfection anyway, what with it seeking to improve forever and never reach an ultimate point
