I shouldn't really comment since I am not a US citizen so it is not my tax money being used but here I go anyway.....
I think it has been well worth the million dollars already just in media coverage alone in the last 48 hours. For comparison, how much gets spent on commercials during the Superbowl? One million dollars is actually quite paltry for the media blitz we have received overnight.
In addition, I think the report is very comprehensive, covered a lot vast amount of information and will be invaluable to us moving forward. Sometimes you have to "spend a bit to earn a lot". In this case, I think it will bring in more money, more attention, more doctors and researchers, and on and on down the line.
From a British citizen, Permanent Resident of Canada, thank you to the citizens of the US. I think your tax dollars, in this case were well spent.
