Medicare Tax or Contribution

ProPublica's Olga Pierce notices that, Orwellian Newspeak style, "among the 15 pages of changes to the Reconciliation Act included in the manager's amendment released over the weekend was a wee name change: references to 'Medicare tax' were deleted, and replaced with the much gentler, and voluntary-sounding, 'unearned income Medicare contribution.'" Which is worse, the tax itself or the effort to camouflage it?
