We all certainly have the capacity for it, but by no means can you say each and every person on Earth gives into it. Rise above it or not, its your choice.
Haven't seen a person (on the Internet or otherwise) who doesn't act in a manner consistent with your description. So far the evidence is pretty strong.
I think you have a very cynical view of things and expect anybody short of being a saint to be a hypocrite. Sure people care about some things while ignoring others, but that doesnt make them indifferent, there is only so much moral bandwidth a person can handle.
