International air tickets!

This question has been lingering in my mind ever since I received my very first international air ticket. Why the heck do they have these tickets so cluttered making it totally unreadable to a layperson?

Why can't they have it well-formatted with arrival/departure time et al highlighted for the benefit of the traveller? This gibberish text couldn't have been etched out purposefully for a system to read too! Because, there is no magnetic stuff whatsoever and it's a plain old-typewrite-style text. What purpose does this serve?

There are so many painful little things in life. But this is one which is painful to every party involved and for no reason. Does anybody have a clue why it is so?
