I have always wondered why the US government never took advantage of this sort of thing to make serious money. Just think of a massive extraterrestrial-themed resort in the desert in the vicinity of Area 51. Think of all the licensing deals.
This is the only way government is influenced. I know, I've worked there.
That is why things like all those Lochness Monster hotels go broke all the time. People start disbelieving that stuff quickly.
