I recently heard that more man-hours went into landing a man on the
moon than any other single endeavour in human history-- in
particular, the great pyramid and the great wall of china were cited
as requiring far fewer man-hours than the apollo program.

If true, I find it very nice that a modern society could mobilize such
large resourcesfor such a huge undertaking. But is it true??

Without looking up numbers, I doubt it very much. Just as one example,
take the interstate highway system. Like Apollo, it has a more or
less one sentence goal "Connect all the major cities of the USA by
good roads". The total resources spent, both man hours and dollars,
must far exceed the Apollo program.
