The truth is more onerous than that. The thing is, they *don't* want that. No major American company actually *wants* to wipe out the middle class. After all, who would you sell your products to if nobody has any money? Companies need a strong middle class and are well aware of that fact. Yet they still work to reduce wages as cost cutting measures for a temporary return. It's blatantly self-destructive behavior that everybody seems to be in on, aware of, wants to stop, but consistently take the wrong routes.
If there were a few guys up at the top in swivel chairs with fluffy cats going "mwaahahahaha" as they plot and scheme, that would be one thing. They could be stopped. How do you stop a society from marching over the cliff - fully aware the cliff is there, fully aware they don't want to fall off it, yet somehow not willing or able to stop themselves from doing it?
