While having a quick look of “Failbook” I found this enlightening status update:
This is one of the reasons why taxing on the basis of a “family” unit instead of an “individual” unit doesn’t make sense to me. By setting up an arbitrary idea of what a family is you ensure that people arrange their affairs to take advantage of that, and you ensure that people that are either unwilling or unable to enter these arrangements struggle.
People pool resources and work together by forming a family unit if they want to. Lets just stick to taxing people as individuals, and let individuals in society make the decision on what type of family unit to set up given this equal treatment – after all it is the individuals that make choices.
