When reviewing older science-fiction, it's generally appropriate to examine predictions. In “This Crowded Earth” the story starts in the late 90s when the Earth's population reaches 6 billion. I was in Biology class in 1998 when the population counter the teacher set up reached 6 billion and I was like “Damn, shit be crowded!”
I've always been a huge fan of Bloch's short stories, so I was a little disappointed at these two novellas (complete science-fiction novels, according to the cover). Both involve such themes as urban decay, over mechanization, reproduction, social this and that, dude on the run... “Crowded” is from 1958 and “Ladies” is from 1968 and they both read that way.
The first novella, “This Crowded Earth” was the better of the two, following various people in the late 20th and early 21st century who are caught up in the social tide of a world that tries to solve overcrowding in a pretty radical way. Apartments are one room, and the only way to get more rooms is to get married and breed, so people do, like bunnies. This book has a guy in a cell chatting up a science-fiction author at once point, which makes it a tad meta and jokey. Oh, and the solution involves injections to all pregnant women to create a race of 3-foot humans who take up less space and food.
“Ladies' Day” has an amnesiac guy frozen during WW3 (in 1971, remember?) and waking up in 2121 where the world is a matriarchy and men are a minority without rights. This story also subverts the genre, although it's not that satisfying. There's some thought, some wordplay (people exclaim “Mary” in place of “Jesus”, menstruation is referred to as “womanstruation”). It's shorter, so I guess you can't really fault it for rushing relationships and delivering exposition in long blocks of monologue.
I already knew Bloch was no typical fellow from his other writings, so it should be no surprise that these two stories take a relatively progressive slant for their times.
As a guy living in the 21st century, it's nice to see that one doesn't have to commute for hours through major city gridlock to work a job for 4 hours and then come home to a box. There are still 7 billion people walking around, though, and that shit is craaaay! We need some damn cities on the moon already! (no, there were no cities on the moon in the book.)
Anyhow, not a total waste of time, but hardly equal to Bloch's short horrors or most of his screenwriting.
