"The organized producers of particular commodities or services will in general attempt to justify the exclusive policies by pleading that they can still meet the whole demand, and that, if and when they are not able to do so, they will be fully prepared to let others enter the trade. What they do not say is that this means merely that they can meet the demand at prevailing prices which give them what they regard as adequate profits. What is desirable, however, is that the demand be satisfied at the lower prices at which others might be able to supply—leaving those now in the trade perhaps only an income reflecting the fact that their particular skill is no longer scarce, or their equipment no longer up-to-date. In particular, though it should be as profitable for those in possession to introduce improvements in technique as it is for any newcomers, this will involve for the former risks and often the necessity of raising outside capital which will disturb their comfortable established position and seem not worth while unless their position is threatened by those not content with theirs. To allow the established producers to decide when new entrants are to be permitted would normally lead simply to the status quo being preserved."
