Name and shame the guitar teacher!!!!
Classical guitar is just for poor people who can't afford a piano (not really, just wanted revenge!!)
In my experience, all instruments carry their own challenges and the thing about classical music over Jazz is that the demands of the improvising musician are very different from a practiced performance of the 'repertoire'. You can't 'fake' Jazz and regurgitating tried and tested lines and patterns is not going to cut it. You have to have a mastery of the instrument and the associated concepts to deliver a rounded performance. Unlike classical music where, if you learn one piece, you have learned it (can't you see I am bitter!).
Learn all the scales and chords you can and TRANSCRIBE, TRANSCRIBE, TRANSCRIBE!!
