See, that's why court proceedings are public, so that the public can verify that courts are fair. It's also why judges are appointed by democratically elected politicians. Who appointed your arbitrator?

And of course the court system is bad and unfair in a bunch of ways. But it's starting from a much better place than secret, forced arbitration.
