Bad quality art files

As a prepress/preflight technician (for 25+ years), I am beginning to a a downward trend in quality art files. Messy, badly planned, badly executed files, with text that looks like it was image-traced by a 2nd grader from a 72 dpi PNG file.  Are any of the newer designers out there getting any training at all in setting up final files for print and print production?  Setups for 4/c Process vs. Flexography vs. Digital print?  I get the idea that all the new art files I'm receiving are from amateurs who have no idea what they are doing.
