Great point. You're never going to start out with everything you want. Maybe the parents oversell kids on this idea or they want their kids to "have it better" than they did. I have actually heard parents say this.
And to participate in the topic, I moved out when I was 17 and the only time my husband and I had to move back in with the reants was for a couple of months when we both got laid off at the same time from the same company (damn Motorola).
I have always been too proud to take money from anyone or help. I still won't even let my parents pay for dinner when we all go out and I have to drive myself in my own car wherever we go.
They think it's silly, but I just hold my independence too tightly I guess.
