The character "Major Major" has a surname of Major, and a double given name of Major Major, and also was promoted to the rank of Major at one point, so his full title and name is "Major Major Major Major", which is the title of the chapter about him. Catch-22 is deliberately silly in places, but is also clearly referring to some real things.
1. FYI, on Hacker News it's impossible to downvote a direct reply to one's comment. 2. I hope you realize that Catch-22 was published 55 years before Trump was elected. 3. I think the "paying people not to grow food" policies Catch-22 mentions came from Roosevelt's New Deal, and seem like the kind of thing Trump would likely oppose.
