Concern over the poor Raceway profitability is appreciated, noted and irrelevant.
Those who frequent Raceways spend as much as they can and/or want to. If it's not motors, it will be something else.
Scarcity of product increases prices and not necessarily actual value.
Increased prices reduce the number of customers regardless of value.
The cheapest products with the highest margin are rentals and parties.
Next are the easily sold RTR inexpensive impulse buy cars that are not designed for racing...a product that has been sorely neglected since the Sixties (but is readily available by the bazillion in the 1/32, 1/43 and HO market).
Finally, the most expensive, least profitable and frequently obsoleted on the wall before they are sold are items specific to organised racing.
Those of you who are customers may care about the business, but you really don't have the same grasp of it as the guy behind the counter.
