Nobody should trust a billion dollar corporation, that's why we have democratically elected governments. All these power hungry fucks counter balance each-other, to some extend at least.
You're equating democracy to presidential elections, that's not the full extent of it. Free press, transparency, independent justice, referendums, etc. are all part of a democratic system. Norway / Denmark / Switzerland do it better than US / UK / France for instance.
