I can give you an idea of why it's so terrible. I'm a professor that teaches multiple classes, I run our department's grad programs, I do various kinds of service activities within the university, I'm the editor of a journal, I collaborate on research with others, and I get media inquiries from time to time. That's the professional side. I have a family, a house, and just lots of other things that require email correspondence.
It's not that the volume of messages needing a reply is so large (though sometimes that's an issue too) but rather the time and energy required is so large. Most things don't allow for a quick one-liner off the top of your head and then going back to work. In some cases, you have to do research and make sure stuff is followed up.
My situation is by no means unique. Be thankful if you don't have to deal with it, because a lot of us do, and it's not by choice.
