Transparency. The ability to see through something. In forms of governance, the ability to see all the necessary elements leading up to and including the decision.
In dictatorships, transparency is unavailable. Opacity rules.
The proper functioning of the democratic form of government exists only where transparency exists. Corruption in the democratic form of government occurs solely where opacity is available. Where transparency is unavailable in a democracy, the decisions become dictatorial in nature.
Dictatorial governments levy taxes to gather in riches for the accomplishment of the dictator’s wishes. Democratic governments levy taxes to pay for services for the good of its electorate, its people, and, its assets.
When transparency is unavailable to the citizens of the democracy, corruption filters through always in the form of excessive charges, and, dividing the spoils among the participants.
With transparency, the democratic form of government earns the trust of its citizens, and, decisions are taken, always at the best price for the quality.
