English actually does have a pretty hefty set of honorifics and titles (mostly pilfered from other languages' pockets), but when spoken, they're usually expected to replace the addressee's name, not be appended to it.

"Doctor, is it serious?"
"Sir, if you'll just move along now..."
"Looks like someone cracked his head right open, Chief.."

Most of the time, adapting Japanese into that format isn't too tough, but there's always exceptions. Why the heck do manga and anime have everyone shouting everyone else's names every five minutes, anyhow...?
