I think Rip may agree with me that a lot of times, people who think they don't have flexibility are actually observing a lack of strength through a particular segment of a range of motion. Most people can do a full squat, but people who "can't go down low enough" are typically really weak at the bottom and as such, they restrict their own movement to keep them from getting into a position they subconsciously know they are too weak to get out of.
