Same reason most people actually want to see Gibson at the end of the headstock and not Epiphone or any other brand. The one thing Gibson has done well... (to their detriment) is instilling shame for playing anything but "authentic" (whatever that's supposed to mean) all negativity aside, people still want to see Gibson on the end of their Les Paul's headstock! But alot of people do not go that route due to cost, or fear of QC issues on something so expensive, or because they do not offer a color or feature set they like or can AFFORD. Almost everyone wielding an Epiphone either secretly or openly wishes it said Gibson... even of the Epi is fantastic in every way, they would still rather see Gibson. But Gibson doesn't seem to understand they could be capitalizing on that. They could be making a Gibson range to compete with Fenders Mexican range... and make an absolute fortune and firmly insert their name and brand in bedrooms everywhere. All the while restoring relations by removing the "exclusionary/privileged/elitist" image they give off. But no, let them keep forging ahead selling to doctors/lawyers, those without (or soon to be) wives or children etc... while the working musician and garden variety player/enthusiast just lust after your product (that arguably isn't that good lately). They need to face facts, people aren't lining up around the block to buy 3-4k production models especially when in some cases the quality isn't there. Not to mention, today's mindset with alot of people is to have many guitars not just one nice one. So,(as an example) people would rather have 4-5 Mexican Fenders as opposed to 1 LP standard for the same cost.
