For six years they have been trying to establish a self-sustaining colony on Venus because space was running out on earth. However no sooner have they sent their colonists than they quit. They try to figure out what makes the resignations keep coming in but can’t come up with any particular reason. It seems to be a matter of psychology when the people think they can get rich on Venus they are not short of volunteers to go.

Excellent story with a little history thrown in!
