No shit, sherlock.
That whoosh you heard was the earlier discussion of the "default" phenomenon of .gov workers, flying over you. "We can't do that, because we've always done it otherwise".
Let's fast-forward from 1938 to now, where those individuals now tasked with wilderness trail are supported by modern safety standards and compensated with more than subsistence food and shelter, in comparison to the CCC era where many/most of said trails were installed. Seems to me like we can't afford as many folks to do that work as we could back then. Also seems to me that, as with any other hazardous work since, productivity has lessened due to evolution in personnel safety management (I can't wait for some clown to claim that I'm saying that's a bad thing...). With the changing of the times needs to come a changing of the means. Goodbye Simonds crosscut, hello Husky.
Burn it all down, and rebuild with a mindset of safety, efficiency, and wholesale slaughter of sacred cattle.
