Blattid makes many points against which I would find no argument. On the subject of Heinlein, maybe I am using the common view of his work, without having read that much of it.However, many of his massive later works do contain a point-of-view character who seems to be not Heinlein himself, but an embarrassingly obvious version of what he would like to have been if he had been born later and been part of his perception of the "Permissive Society" of the Sixties. These father-figures who are still highly potent, and attractive to strings of young girls are indeed a very pleasant fantasy (speaking as a male now approaching his 54th year!) but it is psychologically revealing to repeat this image so many times.
Hoping Blattid enjoys "King of the City". I have also just read "Letters from Hollywood" after searching for it for many years, and I loved it too. Is California really like that?
