QUOTE : One of the incidental benefits of price sharing and competition is that people don't tend to see themselves as rivals, nor do they develop the kind of hostility that rivalry can bring. For example, much of the labor force and building materials needed to build a Protestant church can be used to build a Catholic church. But if a Protestant congregation is collecting money to build their church, the concern will be how much money they can raise and how much they will need to build the kind of church they want. Construction prices may force them to forego some of their more elaborate plans in order to stay within the limits of what they can afford. But they are unlikely to blame Catholics, even though the competition with them for the same building materials drives prices higher. If, on the contrary, the government built churches and distributed them among the different religious groups, Protestants and Catholics, they would be rivals and neither of them would have any financial incentive to cut their construction plans for the benefit of the other. Instead, each would have an incentive to justify, in the strongest possible way and in favor of their needs, the mobilization of their followers in the political arena, to insist on receiving what they want and to oppose any intention to reduce their plans. . The scarcity of materials and labor would still limit what can be built, but that limit would be imposed politically and seen by both groups as a result of their rivalry.
