Semantic Conundrum

During the McCarthy Era, when Americans were incredibly concerned with and fearful of Communism, the top marginal tax rates in the U.S. usually exceeded 90%. Currently, if Wikipedia is serving me right, the top marginal rate is 35% and much of the kerfuffle between our presidential candidates involves small percentage point changes. If increasing the top marginal rate to the upper thirties makes one a 'socialist', what words should we reserve for the mid-century ninety percenters who were ostensibly fighting Communism tooth and nail?
