I see your point, but I'm going to play devil's advocate.
The Fellowship used Gollum in the most effective way - Gollum did the job and then conveniently dropped himself and the ring in lava. They didn't even pay Gollum for his work as a scout - it was his desire for the corrupting thing that enslaved him, both to the lower evil and to the higher good. Is there a way we can similarly use the corrupted things parasitizing the west? Idk, maybe, may be worth looking into.
Mercy and parasitism can also be seen as a blessing. One of my mottos is, "all true blessings appear as curses." If we can withstand the hardship, then we can be stronger because of the effort.
Marxism took the world by storm back when the world had no defenses against it. Defenses are strong arguments and people organized and ready to respond when it appears in the real world.
Most policies shouldn't exist, but the good thing is, they force us to become more efficient by imposing inefficiencies on us. Compliance with policy raises costs and funds terrorism - businesses must compensate by becoming more efficient, serving more people, and improving their security and communications for when the terrorists come knocking.
Would we actually be better off without the parasites? For a moment, probably, and we'd probably have a momentary golden age. But we'd stop evolving... Our enemies make us strong. Love your enemy.
Just playing devil's advocate. I also was/am quite persuaded by Nietzsche's critique of Christianity.
