As a concrete example, suppose that 100 years ago, a bunch of racist politicians passed a minimum wage law in order to price a local ethnic minority out of the labor market. The minimum wage exists within that historical and social context. However, if more recent research shows definitively that the minimum wage is now improving employment outcomes for that same ethnic minority, the historical and social context would appear to be irrelevant.
