It is quite commonplace within the political culture of liberal democratic societies to view politics and politicians in an exceedingly negative light. Many people will often speak of how all politicians are “crooks”. Furthermore, we often hear people using the term “politics” to refer to any situation involving illegitimate bias, partisanship or unfairness. For example, when people refer to a workplace as “political,” they tend to mean that people are not rewarded by their merit, but because of other factors including manipulation and deceit. Consequently, it seems that “politics” as a subject occupies a particularly negative place in the popular imagination of liberal democratic society. However, the trouble with this attitude towards politics is that while it rightly condemns the untrammeled pursuit of self-interest within politics, it cannot explain why politics should not operate according to self-interest, when the broader economy largely operates according to this logic.
Within liberal democratic culture it is seen as perfectly legitimate to try to secure the best possible job for yourself as long as you do not violate the rights of others. To a large extent this has become the dominant maxim of public morality within liberal democratic culture. But while letting the relatively uncontrolled pursuit of self-interest dominate within the broader economy may be acceptable, it leads to a deep problem at the level of politics. For example, when politicians are motivated by the need for re-election they will pass legislation that ensures their re-election, rather than legislation that best serves the interests of all. Furthermore, the person who switches his views at a financial institution to get a promotion or to keep his job, is viewed is prudent, but a politician who takes a different position to ensure re-election is viewed negatively. This disconnect between politics and the broader economy show that the morality of the broader economy is inadequate to govern politics in that we think that there is something wrong with a politician putting career self-interest before the common good, whereas it is legitimate for a person working within the broader economy to do this. Consequently, politics seems to require a more robust morality than the mutual pursuit of self-interest. Rather, in order for politics to reach its moral potential it must operate according to some kind of commitment to the common interest to ensure that legislation is passed that actually serves the common interest.
The trouble is that within liberal democratic culture there seems to be very few voices who speak of the importance of being committed to the common interest, rather at one moment we seem to view politics as just another job that should operate according to the same logic as others, but at the same time we seem to hold politicians to a higher standard, but without being able to explain why they should be held to a higher standard. Consequently, we need to recover the distinction between the morality governing the broader economy, and the morality governing politics so that we adequately grasp the differences between these two realms. If we fail to grasp the difference between these two realms then our criticism of politics will seem incoherent, as we will be criticizing politics and politicians for engaging in actions that are perfectly legitimate outside of politics, without being able to explain why politicians should not engage in these actions while they are involved in the practise of politics.
