It's a very critical consideration of course. There are all kinds of implications, both on the spending and the revenue side. In terms of who does unpaid work in the economy, for example, families have a lot to say on how that unpaid work gets organized. The ways in which taxation affects households, and government spending affects households.... There are all kinds of family dynamics there. There are many ways in which the way families are constituted and how they function will affect the gender implications of budgets.
Those can be very sophisticated topics, if you really want to get in to the more subtle issues. I'm only saying that today we could do a lot, even before we've worked out all the subtleties about how exactly families work.
