Roman aqueducts, modern railroads, the moon landing, the LOTR films, CERN, or Wikipedia...
This seems like an open-and-shut case of failing to look for disconfirming evidence.
All right, but apart from the sanitation, medicine, education, wine, public order, irrigation, roads, the fresh water system and public health, what have the bosses ever done for us?
The moon landing is definitely a fruit of war efforts.
Wikipedia is the opposite of a top-down process.
Aqueducts and railroads: responded on a sibling comment.
LOTR films: I don't even know how it relates to the point, but it's funny that you bring a cultural landmark that it's an adaptation of the works of a single individual.
