Conspiracy theories have become entertainment. They are rooted in the way our brains evolved. Our brains evolved to match patterns so that we can survive in an environment of cluttered information. You always see faces in clouds - NOT clouds in faces. One of the big problems in a troop of 120 roaming primates is trying to figure out what everyone is up to. A rich nutritional "find" might be kept secret from the troop by individual members so they can exploit it for themselves without having to fight for their food. These individuals might share their information with select allies who regularly reciprocate when they find a choice food source. Another "political" problem is access to mating opportunities. Men in power (often ugly) are desireable to females. Nature invests in eggs not sperm.
This is why people believe in Gods and Demons and Invisible souls that are in control. No one has much control because it is impossible to get the right information. There are conspiracies but they tend to form associations where they become each others own worst enemies. There is NO master plan. The master plan is in our own evolutionary heritage. It's called greed. And it fails because the higher you get the more you are a victim of your own hubris.
History is littered with dictators torn apart by their subjects.
Convergence of bad things is easy to explain. Shit happens. And sometimes a lot of shit happens.
Democracy has the right idea. Keep stirring the pot.
