I remember how angels - well, the Valar -- were handled in the Silmarillion. They ultimately returned to Middle Earth to defeat Morgoth when Earendil begged them to help. They did beat him, but it broke the world in the process. If for-real angels are so powerful that even the shortest appearance by them in the mortal world can cause widespread devastation, they have good reason not to come a-running whenever someone calls for help.

It's one of the more interesting reasons for why they don't hang around a lot.
