There are real reasons to distrust governments and corporations. There really are plenty of powerful people acting in their own interest, often to the detriment of others. There are, in real life, legit conspiracies and cover-ups. Tuskegee. Watergate. That weird thing where Volkswagen faked its emissions test results. But real conspiracies are different than the type of conspiracy theory that takes on a life of its own, divorced from fact.
