Asking the question

The presentation on the ELCIC's restructuring plans last night was good insofar as it went i.e. it's good to consider how things can be done more effectively and efficiently to avoid overlaps and gaps.
This restructuring appears to be motivated mainly due to a decline in resources and a finances being given to the National church and to a lesser extent the Synod. However, a lack of finances is merely a symptom that belies a deeper issue and until this question is addressed the problem will continue.
The question is this: If congregational giving has steadily increased over the years (despite a decline in membership and various economic trends) and giving to the Synod has remained for level for the most part, why has giving to the National Church dropped so drastically over the past decades?
Shortly after I was ordained, a senior pastor told me that when people believe a ministry is doing the work of God, money is never an object. Anecdotes and personal experience have proved this true for the most part. Of course there are exceptions. But there is a difference between people being unable to give and unwilling to give. I submit the ELCIC is facing the latter. Why?
There is a range of speculation as to "why" the membership is unwilling to give. Until this is addressed and the support of the membership regained (that's a whole other topic), restructuring, no matter how well planned and thought out amounts to little more than rearranging deck chairs.
