Who writes the test questions? Who administers the test? Who grades it? How random is the random choice? Who determines what cutoffs to use as the population size changes? You'll start to see gaming of the test, where those with resources either get involved in the administration or devote their time to perfecting their offspring's change of getting in that top 0.1 percent. Eventually, those without resources will be wholly unable from achieving scores necessary to be in the top 0.1 percent. You'll have an entire class of people who will either be part of government or feasibly able to join as members die, retire, or finish their terms. They will self-seclude as they have little to gain from interacting with the 99.9%.
