Just like the proliferation of cheap musical instruments diluted the value of the "pro" rock'n'roll bands. Nowadays any random dude with a cracked version of Illustrator can call himself a designer. And, they will be able to generate designs as good as 90% of the designers from back in the day. (See Sturgeon's Law). Only ability with scissors and glue and an expensive drawing table are no longer a requirement.

For a comparison, check out this post from an old/ex-pro cover band rocker. Title of the thread was "Who is responsible for bands making peanuts?"
