Many people have argued that an income tax should be​ "marriage neutral," that​ is, two people should pay the same total tax whether they are married or they are single. Suppose Amanda earns​ nothing, Ben earns​ $60,000, and Cathy and Dylan each earn​ $30,000. They are all single. Amanda pays no tax because she has no income. If they all live in a country that has a progressive income​ tax, which will be​ higher: the tax that Ben pays or the sum of the taxes Cathy and Dylan​ pay?
