"Sure they are. I assure you that the priest who is fully supported by his congregation is taxed on his "earnings"."
Do you read stuff before you post?
What does "often do not earn any money" mean to you?
Also, there's a difference between joint filings for a family and "not earn(ing) any money". Besides, who said housewife? What about the unmarried woman with 5 kids and not working getting state and federal aid? What about the infirm? Transferring of government benefits (paid by actual 'tax payers") from one federal, state or pocket to the other could HARDLY be called "paying taxes". I'm not calling anyone out who happens to be in a situation that requires aid, but it is disingenuous to really try to call them "taxpayers".
