“While withholding income at the source was more efficient, it also made the system more opaque and the tax bite less obvious. This is one of the main reasons [Milton] Friedman’s wife, Rose, also an accomplished economist, vehemently opposed its introduction. Like some mistakes married men make, all indications are that she didn’t let him forget it. ‘Rose has never forgiven me for the part I played in devising and developing withholding for the income tax,’ he once said.” – Jason De Sena Trennert
