In a politicians rise to power, ethics often get in the way. To get elected, they must tell the voters what they want to hear and then trust them to forget what was promised after they get elected. Give a politician campaign contribution and you will likely be rewarded a with benefit paid for by someone else's money.
Trusting a man with power is like trusting a wolf to protect the sheep. Unfortunately the hungriest wolf is most likely to get the job.
There are two kinds of people in the world today; there are the predators and the prey. Most of the people have volunteered to be exploited due to their ignorance and apathy.
