[General Sci-Fi] Why are aliens always attacking Earth for its resources when mining the Sol System's asteroid would be more economic?

Seriously. I've listen to enough science podcasts to know that asteroids are full of the minerals and metals that high-technology societies want...and they aren't covered with pain in the ass nuke-wielding ape-men.
