I disagree. SLS has nothing to do with the Apollo program. It's built mainly from Shuttle parts, so everything they need is somewhat there already. If you compare that to SpaceX's starship which needed to develop a completely new engine from scratch, it's laughable how slow the progress is. But as somebody said it's a jobs program. And just because you need to manage a relationship with the government doesn't mean your engineers can't do a good job and there are clearly several issues (see e.g. https://mobile.twitter.com/SciGuySpace/status/13714885009027...)
