In my experience, because they don't solve the real, hard problems, slow down work, and make it harder to view a good chunk of code at a time. Typing is not what makes coding hard, it is coming up with the proper algorithms, data structures, architecture (e.g. coupling), tests, etc. Typing is faster than dragging icons and filling in properties. Text is denser, so you can view more of your program at once, and in an expressive language can be quite descriptive.
