NASA's problem with the SLS is not really its high cost. A 'high cost' is strictly relative.

NASA's problem is lack of funding. That is something that can't be fixed in today's world. Because the US just does not have the amount of spare cash lying around like it did in the 1960s.

That lack of NASA funding is why I predict that the US will never again put men on the Moon, no matter what all the pundits try to tell us. There just ain't no spare cash, period.
