I've read an interesting story in the late 90's, but the book was already 20 years old. So the story was written earlier than 1970's.
What I recall about it:
- All starts with some kind of sorting machine similar to the one in the Profession story by Asimov.
- It's a sci-fi story about space adventures and hyperspace travel.
- And last thing that I remember, there was a lousy auction for the main hero, where they bought a worst possible planet.
