Sure, but it was burning congressional pork as fuel and cost only the occasional human sacrifice.
A single RS-9 engine -- one of five used in the SLS -- costs more than an entire Falcon 9 launch with payload, taxes, and profit!
Starship is similarly frugal. Its construction is simpler, it is made of cheaper materials, it uses a cheaper fuel, etc, etc...
“Any idiot can build a bridge that stands, but it takes an engineer to build a bridge that barely stands.”
Because we haven’t seen a single re-use of a starship yet nor any significant payload brought to orbit, or the orbital refueling turn around and launch cadence necessary to even achieve 1/10th of what Musk suggests is “possible on paper”.
Super-heavy is being wasted on a potential dead end 2nd stage in my opinion.
