A slightly different viewpoint is that when GA occupies a significant portion of ATC and FAA time and the revenue is not so important (ie, the USA) the industry tends to receive a significant amount of attention. When the priority is the money and GA don't contribute much of the green stuff for AsA or CASA(ie, Australia), then understandably, that portion of the industry doesn't receive much attention and tends to be viewed as a royal pain in the rrrrrrrr.
