The People will, in general, always abdicate their individual power. Few can gather the necessary information, absorb it and form their own opinion and act upon it while living a life, working at a job and raising a family.
The only way to "check" power is to distribute it as equally as possible. And we cannot control which entity people will hand their power to. It will invariably become concentrated.
And human nature says that power corrupts.
