Related to bottlenecks: Population bottlenecks
A marked decrease in gene pool diversity due to a low number of genetically distinct individuals in the population, i.e., a population bred from 2 individuals has far fewer variables on the allelic loci—a bottleneck—than a second population bred from hundreds of individuals

bottleneck

a period in the history of a population during which the number of individuals is reduced to a low number, perhaps by disease or extreme environmental conditions. As a result RANDOM GENETIC DRIFT may occur in the population. See also FOUNDER EFFECT.

To return to Fishkin's opportunity nomenclature, the appeal of these proposals is that they help people with disabilities get both through and around disability bottlenecks. They do so by helping people with disabilities see work as an economically superior option to benefits and, more generally, by incentivizing people with disabilities to give up benefits in order to work.
