If one looks at the works of the major apologists for capitalism, Milton Friedman, for example, or F. A. Hayek, one finds the focus of the apology always on the virtues of the market and on the vices of central planning. Rhetorically this is an effective strategy, for it is much easier to defend the market than to defend the other two defining institutions of capitalism. Proponents of capitalism know well that it is better to keep attention directed toward the market and away from wage labor or private ownership of the means of production.
