The Democratic Republic is failing the test of history unfortunately. Democracies are not proving capable of disciplining themselves and living well outside of its means, all of them are in debt, unfortunately I believe the next century will probably be dominated by the authoritarian systems that while not as productive or creative as free societies they have far greater abilities to defend their borders, economies, culture and harness what they have via command and conformity to out maneuver societies that require consensus to move.
This quote is attributed usually to Alexander Fraser Tytler but has been attributed to Alexis de Tocqueville, either or it may be how it unfolds:
A democracy is always temporary in nature; it simply cannot exist as a permanent form of government. A democracy will continue to exist up until the time that voters discover that they can vote themselves generous gifts from the public treasury. From that moment on, the majority always votes for the candidates who promise the most benefits from the public treasury, with the result that every democracy will finally collapse due to loose fiscal policy, which is always followed by a dictatorship.
The average age of the world's greatest civilisations from the beginning of history has been about 200 years. During those 200 years, these nations always progressed through the following sequence: From bondage to spiritual faith; From spiritual faith to great courage; From courage to liberty; From liberty to abundance; From abundance to selfishness; From selfishness to complacency; From complacency to apathy; From apathy to dependence; From dependence back into bondage.
Not sure if we are at complacency to apathy or apathy to dependence yet.
