Understood.<p>However, when making a comparison it's generally safer to take into account the context of what you are comparing. In this case the effort, both private and public needs to be presented within the backdrop of what exactly is happening.<p>Because as you analyze the effort and its accompanying effectiveness you're also going to have to put that effort in context. If in Haiti there are X number of injured people treated and in Katrina there were Y number, how do you establish a direct comparison? Like what percentage is Y in relation to total injured? How's X compare to that?<p>You can go down the list, and you'll eventually have to come to quantifying the catastrophic event in order to put the response in perspective and measure its effectiveness.
