A democracy is direct government ruled by the majority (mob rule). Democracies are only concerned with group wants or needs (the public good).
Lawmaking in a Democracy occurs rapidly requiring approval from the whim of the majority as determined by polls and/or voter referendums. A good example of democracy in action is a lynch mob. Think of it as two wolves and a lamb voting what to have for lunch.
Democracies always self-destruct when the non-productive majority realizes that it can vote itself handouts from the productive minority by electing the candidate promising the most benefits from the public treasury. To maintain their power, these candidates must adopt an ever-increasing tax and spend policy to satisfy the ever-increasing desires of the majority. As taxes increase, incentive to produce decreases, causing many of the once productive to drop out and join the non-productive. When there are no longer enough producers to fund the legitimate functions of government and the socialist programs, the democracy will collapse, always to be followed by a Dictatorship.
Madison warned us of the dangers of democracies with these words,
"Democracies have ever been spectacles of turbulence and contention; have ever been found incompatible with personal security or the rights of property; and have in general been as short in their lives as they have been violent in their deaths..."
"A wise man will not leave the right to the mercy of chance, nor wish it to prevail through the power of the majority. There is but little virtue in the action of masses of men." Henry David Thoreau (1817-1862)
Our military training manuals used to contain the correct definitions of Democracy and Republic. The following comes from Training Manual No. 2000-25 published by the War Department, November 30, 1928.
The manuals containing these definitions were ordered destroyed without explanation during the President Franklin D. Roosevelt administration.
