I shoot Fuji, so I'll speak to Fuji. Fuji is a bit of a niche camera. It is designed to look retro and to operate similarily. All the primary controls, aperture, shutter speed, ISO, et al, are directly and manually activated. Manual controls must cost more to implement than menu driven controls. Fuji cameras have much more metal than similar dSLR's, Fuji XF lenses are all metal and Fuji has a much smaller marketplace, making 100,000 Fuji's must be more expensive than making 1,000,000 dSLR's. (Economy of scale.)
In Fuji's case, yes they are more expensive than a comparable dSLR, but I can see where that extra money is going to.
