Democracy is based on Abraham Lincoln's principal than you 'can fool all the people some of the time, and some of the people all the time, but you cannot fool all the people all the time. If a government is corrupt and fails to improve people's lives, enough citizens will eventually realise this and replace the government. But government control of the media undermines Lincoln's logic, because it prevents citizens from realising the truth. Trough its monopoly over the media, the ruling oligarchy can repeatedly blame all its failures on others, and divert attention to external threats - either real or imaginary.
When you live under such an oligarchy, there is always some crisis or other that takes priority over boring stuff such as healthcare and pollution. If the nation is facing external invasion or diabolical subversion, who has time to worry about overcrowded hospitals and polluted rivers? By manufacturing a never-ending stream of crises, a corrupt oligarchy can prolong its rule indefinitely.

The manifest, the avowed difficulty is that democracy, no less than monarchy or aristocracy, sacrifices everything to maintain itself, and strives, with an energy and a plausibility that kings and nobles cannot attain, to override representation, to annul all the forces of resistance and deviation, and to secure, by Plebiscite, Referendum, or Caucus, free play for the will of the majority. The true democratic principle, that none shall have power over the people, is taken to mean that none shall be able to restrain or to elude its power. The true democratic principle, that the people shall not be made to do what it does not like, is taken to mean that it shall never be required to tolerate what it does not like. The true democratic principle, that every man‘s free will shall be as unfettered as possible, is taken to mean that the free will of the collective people shall be fettered in nothing. Religious toleration, judicial independence, dread of centralisation, jealousy of State interference, become obstacles to freedom instead of safeguards, when the centralised force of the State is wielded by the hands of the people. Democracy claims to be not only supreme, without authority above, but absolute, without independence below; to be its own master, not a trustee. The old sovereigns of the world are exchanged for a new one, who may be flattered and deceived, but whom it is impossible to corrupt or to resist, and to whom must be rendered the things that are Caesar's and also the things that are God’s. The enemy to be overcome is no longer the absolutism of the State, but the liberty of the subject. Nothing is more significant than the relish with which Ferrari, the most powerful democratic writer since Rousseau, enumerates the merits of tyrants, and prefers devils to saints in the interest of the community. For the old notions of civil liberty and of social order did not benefit the masses of the people. Wealth increased, without relieving their wants. The progress of knowledge left them in abject ignorance. Religion flourished, but failed to reach them. Society, whose laws were made by the upper class alone, announced that the best thing for the poor is not to be born, and the next best to die in childhood, and suffered them to live in misery and crime and pain. As surely as the long reign of the rich has been employed in promoting the accumulation of wealth, the advent of the poor to power will be followed by schemes for diffusing it. Seeing how little was done by the wisdom of former times for education and public health, for insurance, association, and savings, for the protection of labour against the law of self-interest, and how much has been accomplished in this generation, there is reason in the fixed belief that a great change was needed, and that democracy has not striven in vain. Liberty, for the mass, is not happiness; and institutions are not an end but a means. The thing they seek is a force sufficient to sweep away scruples and the obstacle of rival interests, and, in some degree, to better their condition. They mean that the strong hand that heretofore has formed great States, protected religions, and defended the independence of nations, shall help them by preserving life, and endowing it for them with some, at least, of the things men live for. That is the notorious danger of modern democracy. That is also its purpose and its strength. And against this threatening power the weapons that struck down other despots do not avail. The greatest happiness principle positively confirms it. The principle of equality, besides being as easily applied to property as to power, opposes the existence of persons or groups of persons exempt from the common law, and independent of the common will; and the principle, that authority is a matter of contract, may hold good against kings, but not against the sovereign people, because a contract implies two parties.

The principle of democracy is a recognition of the sovereign, inalienable rights of man as a gift from God, the Source of law.

Democracy is based upon the conviction that there are extraordinary possibilities in ordinary people.

Democracy has no place for the kind of justice implied in an eye for an eye and a tooth for a tooth. Democracy is a system for the resolution of conflict, not for vengeance. Simple black-white notions of right and wrong do not fit into democratic politics. Political controversies result from the fact that the issues are complex, and men may properly have differences of opinion about them. The most terrible of all over-simplifications is the notion that politics is a contest between good people and bad people. Democracy is based on a profound insight into human nature, the realization that all men are sinful, all are imperfect, all are prejudiced, and none knows the whole truth. That is why we need liberty and why we have an obligation to hear all men. Liberty gives us a chance to learn from other people, to become aware of our own limitations, and to correct our bias. Even when we disagree with other people we like to think that they speak from good motives, and while we realize that all men are limited, we do not let ourselves imagine that any man is bad. Democracy is a political system for people who are not sure that they are right.

The main principle of a democracy is that the rights of any one group, be it minority or majority, are connected with the rights of all groups.

Democracy arises out of the notion that those who are equal in any respect are equal in all respects; because men are equally free, they claim to be absolutely equal.

Theoretically "democracy" means popular government; government by all for everybody by the efforts of all. In a democracy the people must be able to say what they want, to nominate the executors of their wishes, to monitor their performance and remove them when they see fit. Naturally this presumes that all the individuals that make up a people are able to form an opinion and express it on all the subjects that interest them. It implies that everyone is politically and economically independent and therefore no-one, to live, would be obliged to submit to the will of others.

Democracy is essentially a means, a utilitarian device for safeguarding internal peace and individual freedom. As such it is by no means infallible or certain.

Democracy is essentially a political system that recognizes the equality of humans before the law.

[Democracy] is the line that forms on the right. It is the don’t in don’t shove. It is the hole in the stuffed shirt through which the sawdust slowly trickles; it is the dent in the high hat. Democracy is the recurrent suspicion that more than half of the people are right more than half of the time. It is the feeling of privacy in the voting booths, the feeling of communion in the libraries, the feeling of vitality everywhere. Democracy is a letter to the editor. Democracy is the score at the beginning of the ninth. It is an idea which hasn’t been disproved yet, a song the words of which have not gone bad. It’s the mustard on the hot dog and the cream in the rationed coffee. Democracy is a request from a War Board, in the middle of a morning in the middle of a war, wanting to know what democracy is.

Democracy means that if this man, you, and I will be trapped on an island, we having a majority of votes will decide that you have to sleep with us. That's the Democracy. And with 2/3 votes we can even put that in the constitution.

If x is the population of the United States and y is the degree of imbecility of the average American, then democracy is the theory that x × y is less than y.

There is no basis for democracy except in a dogma about the divine origin of man. That is a perfectly simple fact which the modern world will find out more and more to be a fact. Every other basis is a sort of sentimental confusion, full of merely verbal echoes of the older creeds. Those verbal associations are always vain for the vital purpose of constraining the tyrant.
