I remember Kes being pretty close to her father, but that's all the family she had, and I think he was dead when she left, wasn't he? All Kes would have to go home to would be maybe some old friends or classmates, whatever, and most of them would be dead. She'd pretty much be going home to a bunch of strangers, even if it was the familiar world. As for people wishing they could go home, I guess it depends on what they have to go home to. Some homes need to be left. I'm not saying my own life is like that, but I wouldn't generalize that everyone wants to go home. I never felt like Kes was homesick when she was with Voyager. She had a chance to stay with the more advanced Ocampans she met, and she still chose to stay with Voyager. She only left because of her growing powers and the risk she posed to ship and crew. While the rest of the crew wanted to go home, Neelix, Kes and Seven didn't have the same goals. Voyager was their home, the only home any of them had. At least Neelix chose to leave for a new life that he wanted, with a wife and stepson. Seven went with Voyager to Earth to begin a new life (and returned to Voyager in the books). Kes did get a better life, and a redemption story in the books to explain her inexplicable actions at least, but I never bought that Ocampa was truly home in her heart anymore. Voyager was her true home in my opinion.
