The thing I disagree with is the tendency to chalk it all up to deliberate conspiracies. Yes, people do deliberately unethical things in the cause of their own advantage.
But human beings have a psychological bias towards trying to personalize forces. The more vague and unknowable, the more we try to put a face to it. IT's worth trying to be skeptical towards this bias.
Yes. You are right. On one hand there are foolish people who write off "conspiracies" as non-existent, yet human history is a drama of uncountable conspiracies. Yet on the other hand there are those who see conspiracies as the cause of everything; they don't see there are larger forces at work.
