My opinion, the easist way to profit is by unique product development
and marketing, or in the service sector. I just can't see making a living
in amateur radio retail... the competition is stiff and the profit margins
are small.

You are a software developer? I suggest you use your talents to develop
something in the amateur software area. Can't off hand suggest more
specifically, but digital radio, digital voice, and even video are areas
one might look into. Then there are the other peripheral products like
logging, QSL, maps, world time and geographical info, radio control,
propagation info, antenna measurement, etc, and a whole lot more I can't
even think of at the moment.. Good luck.
