Sincere Question For “Keynesians”

I asked this in the preceding post but here’s a sincere question for all “Keynesians” who believe in “Keynesianism”, and who genuinely believe in something called “stimulus”:

Why wouldn’t a Moon Program count as “stimulus”? Why wouldn’t a Anything Program count as “stimulus”?

With a Moon Program, the government would be spending money. On something. And at least some of the money would conceivably be ultimately used to pay for some jobs. Isn’t that “stimulus”? As far as I can tell it meets all the criteria for being “stimulus” (let’s tick off the criteria: government spending money? – check; on something? – check; at least some jobs conceivably resulting? – check).

So then why is President Obama stupidly (and, perhaps worse, unkeynesianly) forcing through this giant anti-”stimulus” measure (scrapping the moon program)? I thought he, and you guys, totally believed in “stimulus”. Because of how seriously true and correct “Keynesianism” totally is. In particular, you all totally believe that (under certain vaguely-defined circumstances, i.e. if “there’s a crisis” or perhaps a “liquidity trap”) it’s an unalloyed good for the government to spend a wad of money. (On something.)

The Moon Program is something. Isn’t it?

Please help me understand. I know I’m not as reality-based and Scientific (and Keynesian) as all y’all who learned about “Keynesianism” in a Unit in your giant large-print economics textbook in your undergraduate econ class, but I’m trying. I want to understand. How can Obama be doing this, and going back on the utterly scientific and unquestionably correct “Keynesian” principles you all hold so dear? Why aren’t you crying out at this betrayal?

Instead of scrapping the Moon Program, shouldn’t we be getting more Moon Program? If there was a plan to go back to the Moon once, how about let’s plan to do it twice. Ten times! Better yet, let’s set up a Mars Program, a Jupiter Program, a Uranus Program, a Pluto Program while we’re at it.

Wouldn’t any of those count as “stimulus”? Which ones wouldn’t, and why not?

I know that the subtleties and intricacies of “Keynesianism” and “stimulus” are lost on a dummy like me. But at least give me some credit: I want to understand. I want to learn. I want to be a better, smarter person. Like all y’all “Keynesians”.
