>One hypothesis is this is largely explained by prevalence-induced concept change in human judgment. What is the evidence that refutes this given the population level changes in attitudes and revealed preferences since the 1960's?
Indeed.
Every minority group in the US is initially seen as "the other". After some point, however, employers that hire "the other" usually find that they can pay them less because there is less demand to hire them, and thus benefit financially, they hire more. As other employers follow suit, over time the salaries go up until they match that of other groups. Similarly, even if landlords initially hesitate to rent to "the other", some will; assuming that there are no unusual problems, over time other housing stock will be made available to them as landlords do not wish to turn away paying tenants.
Their children benefit. The first generation of manual laborers and farmworkers begets the second generation of policemen, nurses, and soldiers begets the third generation of doctors and lawyers and professors.
In the US this has happened to Irish, Italians, Germans, Russians, Jews, Asians, Indians, and Latinos. This natural process has not organically happened to blacks (or has happened in substantially less numbers), despite the latter having the benefit of US citizenship and command of the English language from birth.
