If an image macro I can't find and read on /co/ is to be believed, it's because the people attending art school have a different view of artistic philosophy. Previously, it was understood that to create "silliness", one needs to have an understanding of basic form and structure to see what can be "corrupted". Pablo Picasso, a modern artist, painted this in his formative years. It shows anatomy, perspective, and lighting, and even the hands are drawn reasonably well. He had the proper training in art in order to create his later masterpieces.
However, the new generation doesn't understand that one has to build something up to break it down. They immediately jump to the end-point, which they believe shows their "expression" and "creativity". It's bizarre, wacky, absurd, and totally ungrounded. This has its merits in some ways, but is altogether a net negative in terms of talent.
Compound this issue of a lack of training with inspiration from anime, learning to draw from tracing other people's art instead of learning proper anatomy, changing one's style to match a particular "hero", and allowing anyone who will pay the course fee regardless of merit to attend university, the end result is... well, what you're complaining about.
