Hey Mike, blame the landscapers for buying all those trimmers and back packs.
Years ago, you'd go to the mower shop for mowers and go to the saw shop for saws. Full line dealers would have saws of some kind, usually Mac or Homelite. But like today, 9 out of 10 of those dealers lacked the focus for serious saw users.
Husky and Stihl had pretty thin catelogs back then, cause they only sold saws. When they introduced trimmers, neither company even made their own, as they both had them private labeled from japan. (Husky's by Maruyama, and I don't remember who did the Stihls). They both sell a lot of other products now, which probably bugs some guys who wish they'd just do saws. But look at what happened to all of those companies that never got beyond saws. Most recently Jonsered which had all the resources in the world but still failed.
It's hard for saws to compete for attention in most stores with $20,000 Z's or $50,000-$100,000 AG tractors, but that's where they landed. Some of those big dealers could probably do a nice amount of saw business if someone at those shops picked up the ball and ran with it. Some do, but most don't.
But
@Homemade makes a key point in that not every dealer is in an area that even has the potential to do decent numbers on the saw side. You can't expect them to get all geared up on the pro stuff if that market really isn't there. I'm lucky in that I live in a hardwood forest, and we have every category of the saw market; logging, arborists, firewood, and the occasional user from the city that probably shouldn't even own a chainsaw. But even in this area, most dealers really don't get it on the saw side. They are exactly what you guys are compaining about; mower dealers who have "some saws over there on the back wall."
