"Power tends to corrupt, and absolute power corrupts absolutely." (Lord Acton)
Presently, we are seeing the manipulation of the media by the powers that be - to mislead and reinforce status quo against the will of the people and their best interests - particularly in the US, Britain, Europe.
"Unconstitutional and unjust coercive legislation and laws, infringing individual rights, must be 'of few days, and full of trouble.' The vox populi, through the providence of God, promotes and impels all true reform; and, at the best time, will redress wrongs and rectify injustice. Tyranny can thrive but feebly under our Government. God reigns, and will 'turn and overturn' until right is found supreme." (Misc. Wr.)
Since God is All-power, attempting to exercise power, no matter how well-intended, without God/Principle/Love, is corrupt, and this corruption leads to self-destruction.
NOTE: We recommend the book, "God & Churchill," (thanks Bob for the suggestion) which describes the power exercised by Sir Winston Churchill within the constraints of the British Parlamentary System, and that of Hitler which was absolute and which ultimated in a debased, inhuman state of self-destruction.
