This is an expected consequence of over monopolization of industry. You lose all the natural power of moderation that comes from the market. With that gone, corruption is left unchecked, regulatory bodies are captured, and collusion is purchased to gaslight everyone over the truth.

You also should never trust any court, in particular, the Supreme Court. A court has no special access to facts, yet it operates with complete authority, as if it's process was entirely without error. They are a compromise that only makes sense when all other civil remedies have been exhausted because there is no mechanism to guarantee an improved outcome from their involvement.

Which highlights the basic point here, any institution of appreciable size and without competition cannot possibly remain uncorrupted by it. It's essentially impossible to build any government institution that is worthy of "trust."
