Many who refute the underclass concept suggest that the "underclass" term has been transformed into a codeword to refer to poor inner-city blacks. For example, Hilary Silver highlights a moment when David Duke, former Grand Wizard of the KKK, campaigned for Louisiana Governor by complaining about the "welfare underclass". The underclass concept has been politicized, with those from the political left arguing that joblessness and insufficient welfare provided are causes of underclass conditions while the political right employ the underclass term to refer to welfare dependency and moral decline. Many sociologists suggest that this latter rhetoric – the right-wing perspective – became dominant in mainstream accounts of the underclass during the later decades of the twentieth-century.
