If Fender is making the same profits across the board, then why would they even bother with MIA's, or even MIM's when they could build nothing but Squiers and make the same money?, doesn't work that way.
Picture that... Fender completely scraps the Fender line, and starts marketing Squiers, VM, CV MIM, MIA etc.
Everyone would start threads about sanding off Fender decals to replace with Squier decals, Basswood would become an endangered species and the bass world as we know it would implode, creating a huge void where only non J and P shaped basses would survive!!!
