The remark "democracy is the worst form of government except all the others that have been tried" is attributed to Churchill, who was also no friend of Socialism. It is worthwhile to consider whether there is a relation between the two. I think there is, and that it is this.
What makes democracy attractive is that it gives a voice in governance to the governed by a supervised mechanical means, the vote. Thus the people are governed by representatives whom they have chosen. The risk still remains, however, that the majority will then exercise the same dictatorial powers exercised by individual tyrants or oligarchs over a minority. To some extent, this is usually controlled by the existence of protective laws, but laws can always be changed, and so the risk remains.
Given that power is acquired in a democracy by means of the vote, the candidates for power will necessarily compete for the largest share of votes from the population at large. This means that candidates will inevitably follow the populist strategy of promising new and more costly benefits to the voters. Given that the process is competitive, the candidates will vie with each other in promising ever more to the voters. Given further that there are always limits to state wealth, even taking into account the ability of the state to borrow or print money, the process must inevitably lead to the offer of the re-distribution of wealth. In effect, the candidates will offer to the voting public at large the wealth of one of its subgroups, that of the most successful.
The implication of this is that democracy inevitably morphs into socialism simply as a consequence of the mechanism by means of which power is acquired.
But Churchill was right that all other forms of government have proven less attractive than democracy. What, then, is to be done?
Perhaps the answer lies in the modification of democracy rather than its replacement.
Since the problem lies in the power-acquisition mechanism, it would seem that this is what should be modified. But how? In some way, what we want is to retain the feature of democracy that fairly allocates power to the governed people, while eliminating the motive to re-distribute the wealth of minorities. The answer is at once both utterly clear and absolutely beyond implementation.
As long as the society allows large contingents of people who do not contribute to the gross national product to vote, the move towards Socialism, a system of centralized government theft, is inexorable. What we want is a system of power distribution that takes into account what the voter has at stake in the system and, more important, what the voter contributes to the system.
What must be changed is universal suffrage, the principle of one person, one vote. It is inevitable that as long as universal suffrage is in place, one or more "parties" will a) promise the wealth of others to the many, and b) attempt to increase the number of the non-producing many as much as possible.
In the U.S.A., the Democrat party has been very energetic on both counts. The current president, Obama, has been quite clear that he is interested in redistributing wealth, a euphemism for institutionalized theft. But the Democrat party has been active since the times of Kennedy and Johnson in increasing its voting base, primarily using the civil rights movement. The welfare policies put in place in those times had the double desired effect of exponentially increasing the number of impoverished and government dependent blacks born, on the one hand, and exponentially increasing the number of government dependent social work functionaries. All of these, it was correctly anticipated, would inevitably vote Democrat.
At the current time, that same Democrat party is working to the utmost to allow roughly twelve million illegal aliens to become citizens, an automatic twelve million additional Democrat votes in one blow.
The strategy is not subtle and it is not new, it has been followed by the Catholic Church for hundreds of years as it has roamed the earth seeking ever new poor, un-educated, primitive souls to enlist in its enterprise.
Karl Marx was both right and wrong. There is a mechanical aspect to the flow of history that, in some cases, does lead inexorably to socialism. He was wrong, however, in his identification of the mechanism. It is not the inner workings of capitalism that move us in this direction, but rather the nature of the political mechanism at play in the acquisition of democratic power.
