A good analysis. What NASA does best is pure research. That's where they need to spend most of their money on. When It comes to human space flight, though, there's too much waste and inefficiencies. Unfortunately, most of the crewed space projects like SLS are based upon the whims of Congress, because government money flows into specific states to keep certain folks employed. It doesn't matter whether they actually produce a product or not. That is why NASA should outsource that type of work to the commercial sector.
