I could agree to this provided that there was a floor. If somebody is impoverished it makes no sense to figuratively take half their one meal a day and half their blanket and half their tattered parka to get their "fair share." If we as a society decided that the murders and rapists get food, shelter, and clothing as a given then so should everybody else as a check to those who would rob everybody and take it all for themselves. The system should largely be supported by those whom it works for. You cannot ask somebody for whom it does not work at all to pay an equal share to support it.
