Governments and corporations are fictional persons. They have no "moral consciousness" of any kind, outside of rhetorical and ideological fantasy.

You continue to believe that there is hope for this modern, post-industrial society. But there is none. We as people have increased the sophistication of our tools and our reach - just as relentlessly as we have avoided the refinement of our own beings.
In the end you don't get Star Trek. You don't even get Starship Troopers. You get Scanner, Darkly And hope there is Valis.
