Dealer profits

For a long time I have thought dealers aimed to make excessive profits. We all know that they have costs such as wages, premises etc.

Maybe I am being unfair? 

I am all for fair profits (after all, this is their business), but I object to excessive profits. In my opinion many dealers and magazines will go out of business in the coming years as most amateurs get old and buy fewer radios. Magazines will suffer as there will be fewer dealers and less revenue.

Maybe the strategy is to make as much money as possible whilst they can?
