This is a different time, with different problems.
Actually, not really, as you yourself show by making the issue the very same 'space versus dometsic benefits' tradeoff that is the same issue then and now.
If the govt. were to take on a huge project now it really shouldn't be going to the moon even if we hadn't already.
I was just about to respond to that by saying you should be consistent and point out you would take the same position on the original moon landing, when that's what you do next:
They should take on a project which would benefit humanity much, much more. In fact they would have been better off doing this back then as well, as by now they would have reaped greater rewards than going to the moon.
This simply puts you squarely in the pro-domestic benefits camp, and the difference I noted is that then, this was able to be defeated as a minority view.
A question is how our political culture has changed, that likely now that would be a majority view and prevent the project.
They should conquer, clean up and control the one part of space that is the most screwed up and threatens this nation's and even all of humanity's future the most.
The human mind.
That sounds an awfully lot like some scary bizarre government project of citizen control.
What in the world kind of 'government project' are you suggesting?
If by that you mean something like a great increase in public education as super-majorities of Democrats passed in the middle of the 20th century, I'm fine with that.
(Of course the right wing wants to jump in here, so let's give them a mention, the John Birch society warns against the government mind control project of fluoride in water. The same John Birch society co-founded by the father with the same sort of ideology as his two sons who are perhaps the most powerful influenced in our country today, behind the very anti-government radicalism I'm discussing, the Koch brothers).
