The Congressional Research Service has issue a report on Resilient Infrastructure; August 2012. As is true of CRS reports it is an impartial assessment. At the very end, the interesting question of incentives is dealt with briefly. Thanks to the Federation of American Scientists for making the report public.

I agree with you Bob. If is not required, it is not going to happen. (Might not happen even when required!)

Diva,
This question has been my mantra for quite a while now. Voluntary programs require incentives. Incentives don’t always have to be monetary, but usually they do. What I believe would be hard to deny is that without incentives of some kind voluntary programs will eventually fail, and fail miserably.
