respects: (a) Each continuously establishes a capitalist form of justice; (b) together they
maximize utility in the form of market efficiency; and (c) each respects certain important
negative rights of buyers and sellers. No single seller or buyer can dominate the market and
force others to accept his terms. Thus, freedom of opportunity, consent, and freedom from
coercion are all preserved under this system.
Several cautions are in order, however, when interpreting these moral features of perfectly
competitive free markets. First, perfectly competitive free markets do not establish other
forms of justice. Because they do not respond to the needs of those outside the market or
those who have little to exchange, for example, they cannot establish a justice based on
needs. Second, competitive markets maximize the utility of those who can participate in the
market given the constraints of each participant’s budget. However, this does not mean that
society’s total utility is necessarily maximized. Third, although free competitive markets
establish certain negative rights for those within the market, they may actually diminish the
positive rights of those outside those whose participation is minimal. Fourth, free
competitive markets ignore and even conflict with the demands of caring. As we have seen,
an ethic of care implies that people exist in a web of interdependent relationships and
should care for those who are closely related to them. A free market system, however,
operates as if individuals are completely independent of each other and takes no account of
the human relationships that may exist among them. Fifth, free competitive markets may
have a pernicious effect on people’s moral character. The competitive pressures that are
present in perfectly competitive markets can lead people to attend constantly to economic
efficiency. Producers are constantly pressured to reduce their costs and increase their profit
margins. Finally, and most important, we should note that the three values of capitalist
justice, utility, and negative rights are produced by free markets only if they embody the
seven conditions that define perfect competition. If one or more of these conditions are not
present in a given real market, then the claim can no longer be made that these three
values are present. This, in fact, is the most crucial limitation of free market morality,
because real markets are not perfectly competitive, and consequently they may not achieve
the three moral values that characterize perfect competition.
4.2 Monopoly Competition
In a monopoly, two of the seven conditions are absent: there is only one seller, and other
sellers cannot enter the market. Two examples are Microsoft’s operating system and office
suite software. As the case of Microsoft exemplifies, such markets are far from the perfectly
competitive model. The operating system market is dominated by Microsoft’s Windows
which had a total global market share of 92 percent in 2010. Microsoft also has a monopoly
in the worldwide market for integrated office suite software where its MS Office suite
commanded 94 percent of the market in 2010. Technically, a company must have 100
percent of the market to be a monopoly. But in practice, a company can do it with lesst.
The key feature that determines whether a company has a monopoly is whether that one
company has such control over a product is whether that one company determines who can
get some of the product and at what price. So, while Microsoft does not hold 100 percent of
either of these markets, most observers characterize its control of these markets as
monopolies.
There are several “barriers to entry” any company that wants to come into these markets
has to overcome. One barrier is sheer total cost and risk: today it costs more than $10
billion to develop a new operating system like Windows and it would be extremely risky for
a company to spend $10 billion on the gamble that it might overcome Microsoft’s dominance
of the market. A second barrier is economies of scale which occur when the amount of
