I agree with what you're saying about the big issues and the 3 sources of deficits. But when considering something like the estate tax cut, it makes sense to consider the 'cost' of it in terms of either borrowing necessary to replace the lost revenue, or the cost of cutting government programs to make up for the lost revenue. The $50 billion or whatever cost of the estate tax cut might be a drop in the bucket compared to the overall deficit, but it should still be dealt with responsibly.
