It's obvious -- Mark Knopfler is making fun of the early mtv stars and their music videos. In the voice of a hard-working appliance mover and installer, he's saying there's no hard work going on with these rock stars and they're not dumb-- they may get a blister here and there (from playing guitar), but they're getting "money for nothing and chicks for free" (groupies), and maybe I "should learn to play the guitar on the MTV." Yes, some of the words are a little harsh and controversial, but this song was written tongue in cheek, and it backfired because it became a huge hit showcased on mtv with a clever music video and won a Grammy for Best Rock Performance of -- forgot the year -- in the 80s, I think. I know the purpose of these posts is writing the meaning of songs, but have you listened to this fabulous band (and Knopfler is fantastic, plays guitar beautifully[listen to Brothers in Arms by Dire Straits], does all the vocals and writes the songs)? Along with Brothers in Arms, listen to Why Worry, The Man's too Strong, Romeo and Juliet -- there are too, too many to name.
