Magic Dirt: Political geography possessed of culturally transformative qualities capable of turning the most primitive barbarians of any ethnicity or religion into productive, law-abiding First World citizens whose beliefs, values, traditions, customs, and behavior are indistinguishable from 1950s-era whites of European descent within a single generation.
Tragic Dirt: Political geography possessed by the evil curses of ancient demons that condemn the inhabitants to cultural, moral, civil, and technological backwardness through no fault of their own or their native cultures, traditions, religions, behaviors, philosophies, or DNA. (NB: coined by Steve Sailer.)
