I don't think so. Michelle at Mystic Water has been putting out fantastic, perfectly blended scents for years. Cold River Soaps also have some superb scents. Oh, and Dr Jon's. But these soaps are not getting the attention that the people making new bases are.They could get along with that game of introducing new scents (like they do now with bases) for a while, but if the scents don't offer something truly unique we'd catch on and stop purchasing them after a while.
I honestly believe we're getting close to that point with all the new bases coming out. Think of it like a base bubble kind of like the housing bubble from a decade ago.
The one area where the American artisans can really step up their game is in the scent department. The first to do it consistently will reap rewards I predict.
