Arthur C. Clarke in '3001' has the idea the people living in the low 
gravity levels of his ring city couldn't visit the Earth itself for more

than an hour or so without severe discomfort, and Heinlein in 'The Moon
Is 
A Harsh Mistress' makes a similar point. Any settlers on low gravity
worlds 
would have problems, but their children, and their children's children 
could well be unable to come back to Earth.
