Keyboard players, good ones anyway with good equipment, are not all that common which makes us in demand. I'd much rather be specialized and unique than common like the sea of wannabe guitar players I am surrounded by. Music stores reflect their market... if they all carried top arranger keyboards then I'd be worried that the region was saturated with both keyboard and/or arranger players thus driving down my demand and wages. Maybe that's just my view because I play for a living.
