Engine failure on final

If you fly final with some amount of power (which I gather most people
do -- I always have) that seems to guarantee that if you lose your
engine on final you will land short, and there's pretty much nothing
you
can do about it. Is that true?

Worse than that, is that I have noticed that many pilots seem to take
off using power... That guarantees that they absolutely will land short
if they lose power... What should we all do about that?
