Speaking only for myself and my parents - the factor here has been land. They both inherited several hundred acres of farm and ranch land, and purchased some land in-town when it was (inflation adjusted) $90,000, and is now in the $2-3 million range.<p>They're both terrible at saving, their combined income was never over 50% of what I'm currently making, yet they have both been retired and comfortably living off these "investments" for 20+ years now.<p>I, on the other hand, am just hoping that I can move to part-time work somewhere in my 60's. I'm hopeful, but it means keeping my current income levels for another 20 or so years, and avoiding any major health or other emergencies.
