Maybe you don't hear from those folks you speak of, who have problems, because they know if they had done some P.M. and upkeep, their break-down could have been prevented. For some people, it is hard to admit they should have 'done something..'
Good observation though.
I have made my living all my life fixing things people broke, or things that just wore out. I know first-hand what neglecting mechanical or wear items can do.
