The Klamaths, in particular, were targeted for termination because they appeared to be prospering. A rarity among Native American groups, the Klamaths were financially self-sufficient, being the only tribe in the US to be funding the administrative costs of the Bureau of Indian Affairs through income tax contributions. By the 1940s, only 10% of Klamath families relied upon public welfare assistance. An economist noted that "the Klamaths were never, since 1918, a 'burden' on taxpayers.". This self-sufficiency was made possible by the richness of the reservation's natural timber resources. The unsuitability of the woodlands for conventional farming had meant that most of it had escaped the fate of being given to white settlers under the 1887 Allotment Act. Consequently, were retained as tribal property.
