That's interesting, but I didn't know that. In any case, that detail doesn't matter because he was obviously being rhetorical - there are no studies showing the White House mail room has unusually high loss-rates. :)
It was rhetorical but he was still wrong - he seems to think science was taken more seriously at that time. It wasn't. Asr already pointed this out - but to add to it even before the "do nothing commission" was started the scientists wrote another letter to the President because he had taken no action on it at all after several months. Then he appointed a commission to do nothing for a good while longer. Then the bureaucracy got started on the org charts and Powerpoints. Er...you get the idea.

He warns that this stagnation will undermine the growth that past policies have relied on.
