Why does Nicholas Cage choose to suck so much?

Here we find the actor Nicholas Cage. A good-looking man. A handsome man. A talented man.
Why does he insist on making so many garbage-y films?! The man can act, (see or Matchstick Men or Adaptation) but he insists on making so many films that leave him looking ridiculous. (See Wicker Man, Ghost Rider or National Treasure:Book of Secrets. And that's this year alone.)
I wonder what kind of career he has decided to pursue.
A few years ago, Nicholas Cage was the "it" man for blockbuster action films (Face/Off, Con Air) but now seems to favor PG-friendly family adventure films. Nothing against that type of film, but why do his performances suck so badly?
Often times his lines feel horribly written. I have to suggest, however, that since it seems to happen to Mr. Cage with such relative frequency, it is average screenwriting in the hands of a particularly dull, uninspired performer.

It is a mystery to me. Care to respond, Mr. Cage?
