There is a searchable Urantia Book

Here is what you can find:
-"poverty and dependence can never be eliminated if the defective and degenerate stocks are freely supported and permitted to reproduce without restraint"

-"The races are purified and brought up to a high state of physical perfection and intellectual strength before the end of this era. The early development of a normal world is greatly helped by the plan of promoting the increase of the higher types of mortals with proportionate curtailment of the lower. And it is the failure of your early peoples to thus discriminate between these types that accounts for the presence of so many defective and degenerate individuals among the present-day Urantia races"

-"52:3.3 It is the prime purpose of the Adamic regime to influence evolving man to complete the transit from the hunter and herder stage of civilization to that of the agriculturist and horticulturist, to be later supplemented by the appearance of the urban and industrial adjuncts to civilization. Ten thousand years of this dispensation of the biologic uplifters is sufficient to effect a marvelous transformation. Twenty-five thousand years of such an administration of the conjoint wisdom of the Planetary Prince and the Material Sons usually ripens the sphere for the advent of a Magisterial Son.

52:3.4 This age usually witnesses the completion of the elimination of the unfit and the still further purification of the racial strains; on normal worlds the defective bestial tendencies are very nearly eliminated from the reproducing stocks of the realm.

52:3.5 The Adamic progeny never amalgamate with the inferior strains of the evolutionary races. Neither is it the divine plan for the Planetary Adam or Eve to mate, personally, with the evolutionary peoples. This race-improvement project is the task of their progeny. But the offspring of the Material Son and Daughter are mobilized for generations before the racial-amalgamation ministry is inaugurated.

52:3.6 The result of the gift of the Adamic life plasm to the mortal races is an immediate upstepping of intellectual capacity and an acceleration of spiritual progress. There is usually some physical improvement also. On an average world the post-Adamic dispensation is an age of great invention, energy control, and mechanical development. This is the era of the appearance of multiform manufacture and the control of natural forces; it is the golden age of exploration and the final subduing of the planet."
