1. Do any of the cost savings recommendations you address come close to $1T/yr impact? This is the scale we should be aiming for.

2. If you think this modeling is inaccurate or incomplete you can directly discuss that. That would be a much more interesting discussion than "it might be incorrect."

That's a great question, and one that should receive similar funding and attention to properly compare.

My hunch is that (a) this study over estimates on the cost reduction side and would not pan out, and (b) improving health should always be a better cost savings than reducing corporate overhead (especially given how piss poor our average health is today).
