Where Has The Economic Profession Been For The Past Fifty Years On Measuring Income Distribution In Rulemaking?

Some fifty years ago, an economist who was deeply involved in conducting benefit-cost analysis of governmental actions opined on the importance of  disclosing the income distribution effects of federal actions.

Read for example this paper published in 1969 which concluded ( p. 5):

Obviously if there exist more efficient ways to redistribute income and if such alternatives are politically feasible, then public works projects should not be justified on the basis of their contribution to this objective. However, it does not follow that their redistributive effects – whether to low or high income classes -should not be assessed and presented to the public.
