Milton Friedman purports in Capitalism and Freedom that the free market allows the individual to express her individual desires, while the democratic system forces conformity.
“From this standpoint, the role of the market, as already noted, is that it permits unanimity without conformity; that it is a system of effectively proportional representation. On the other hand, the characteristic feature of action through explicitly political channels is that it tends to require or to enforce substantial conformity. The typical issue must be decides “yes” or “no”; at most, provision can be made for a fairly limited number of alternatives. Even the use of proportional representation in its explicitly political form does not alter this conclusion. The number of separate groups that can in fact be represented is narrowly limited, enormously so by comparison with the proportional representation of the market.”
Although Friedman argues for the benefits of proportional representation in the market, the economic system can potentially arrive at a similar conclusion as the political system. Consider the situation of the carbonated soda market, where advertising similarly enforces substantial conformity by raising the barriers to entry. Coke and Pepsi hold over 70% of the market share. This sounds dangerously similar to the current political landscape in the United States, with Republicans and Democrats holding over 60% of the “voter market share.” 36% of registered voters are Democrats and 27% are registered Republicans. The competitive landscape is actually slanted more in favor of Coke and Pepsi than our often-criticized bi-partisan political system.
The point that Friedman is trying to make is that 49.9% of the country may be forced to conform to a political situation to which they are opposed. Obviously, if Coke has a majority market share, you are not forced to consume only Coke. However, Friedman argues that the free market constitutes a system of proportional representation, but that is not consistent in the Coke/Pepsi situation. Due to wide awareness of Coke as a result of advertising expenditure, the consumer has a higher subconscious disposition to purchase Coke. It is not the result of actual product preference, but rather brand preference. Even if a company launches a cola competitor to Coke that is a healthier alternative with the exact taste, it will likely fail due to consumer’s requisite knowledge of the Coke brand. Essentially, a consumer purchasing RC Cola has the same effect of a citizen voting for the green party. The consumer is forced to conform to an economic situation in which they potentially are opposed, but is unable to view or obtain alternatives due to Coke’s stranglehold on the market.
One could argue that the consumer is not truly forced to consume Coke; she could simply purchase RC Cola in the supermarket. However, what about the situations in stadiums, theaters, or restaurants where there is only one option? These venue providers will rationally select the most prominent brand in order to appease the most consumers, and thus select Coke. But this leaves the consumer with a ‘yes’ or ‘no’ choice in those certain environments; the exact situation in which Friedman condemns. Thus, while liberal economists criticize the conformity in politics and espouse the virtues of the competitive marketplace, both systems are equally susceptible to the concentration of power.
