So what? who cares where he got the money? Where did NASA get the money?? I don't see you adding the entire cost of every technical advance since fire to SLS. Dude, get a grip. Again, what are you talking about? And the bolded parts are where we have the crux of the issue. SLS is too expensive. You can have it, or you can have robust science missions like the ones mentioned below. Golden Spike is a commercial venture and has no bearing on SLS or NASA's budget, unless NASA at some future point purchases services from them - probably at a cheaper rate. Oh, and that's a great article you linked to. I especially like how Robert Clark took it apart in the comments section.
