Only so much of it can be explained by Supply and Demand but much of it is people just being bots.... Mainly before it wasnt so much of a thing even with EBay or MusicGoRound but now with Reverb.....and everyone becoming a bot......buying online only....and online buying is not bad but its just changed guitar culture and selling in some ways that are not always so positive iMO..... Before people used to be cool.....and there are still cool people. Many of the dudes here on the forum are not going to sell stuff at these stupid prices these jokers on Reverb do....but now Reverb made people bots....and well Reverb is cool too....but just people being bots is not...and its not really a GC thing its a thing Reverb did....and even then who else can we or the bots blame for being and becoming bots.......but themselves/ourselves.....people have a choice not be a friggin bot....but on mass they choose to become one....thats the problem.... The willingness to become a part of the Amazon/WholeFoods/Iphone Borg-Collective....by the vast majority.....and just going along with it..... This is what guitar culture and players have allowed in general for it to get to this point ImO..... Its mainly that people are just bots now and willingly go along with this crap........ Its not really the companies fault so much as those feeding that culture, being a part of it and becoming a full on Flipper/Dolphin/Bot when it comes to flipping......flipping is okay...but please dont go Full Flipper/Dolphin/Bot......this is a big part of the reason the used marker is where its at.....and well its kind of to late for that for the majority of the music industry now but aside from Supply and Demand which I understand, these prices especially for used is just ridiculous and irrationally exuberant even for these times......and its not just the companies faults....guitar players have their role to play as much as companies do when it comes to the root of this problem IMO.
