AM can have as good a fidelity as FM and in narrower occupied bandwidth.  Consider the requirements for FM stereo and the fact that the L-R channel is AM.  Yes, it's DSSBSC, but AM non the less.  I will agree with the (unfortunate) AM noise issues in the real world when it comes to AM reception, but that doesn't alter the facts.  As far as AM transmitters - Have you ever proofed an old Raytheon RA 250 or 1000?  Amazing transmitters.  RCA BTA-5F's were also pretty good, once you remove the splatter filter, which wasn't necessary with a decent processors.
