Your article is insightful. However, it is quite inaccurate to define a whole industry with your singular experience. Not all Industrial Designers are created equal. Many companies now hire industrial designers to be key strategists, design researchers, ethnographers, and business systems strategists. Their job is not to make anything look "pretty" or as you mention "dress it up." It is to do formulate the requirements of products, systems, and services from a human-centered POV. This comes before any engineering takes place.
As mentioned above in another review, it is somewhat offensive to the industry to say that an industrial designer's job is to just an "applied art" and "dress it up."
You may want to investigate companies such as BCGDV, Microsoft Inclusive Design, IDEO, Frog Design, Tesla, Smart Design, RCA, RISD, ArtCenter, Standford D-School, etc. They all convey a different definition and role for the Industrial Designer.
