You have to take each case as it comes, but I do find that people who have moved out, or even moved region are more rounded in their attitudes to most things.
Living at home for an extended time means you only have first hand experience of one way of living, one set of standards. By the time I was 25, I'd lived with my parents, my university hall and house mates, alone, and with my husband, in four different places.
I have friends who lived with their parents through uni and now live in the same suburb they grew up in, living exactly the same lives that their parents did. Because I grew up in a rural area, all my childhood friends had to move away to learn and earn, and there's just something a bit more about them than people who've only known one way of life.
(oh, and there was no difference in our abilities to buy houses either)
