This is more of a technology question. So I understand that if you use daylight balanced film under tungsten light, the colors are off. Furthermore, it's impossible to correct fully in post processing, either with filters in a darkroom or corrections in Photoshop. What makes correcting white balance on digital raw files superior and more correct?
As I understand, digital sensors (for the most part) have RGB filters in front of individual pixels, and the image is reconstructed from the Bayer filtered data. If I got it correctly, adjusting the white balance on a raw file is essentially adjusting the gain on the individual R, G, or B channels *in post* to correct for color temperature differences. Why can't you do this the same way in Photoshop (or with filters in the darkroom) with a color negative. Either way, film or digital, you're capturing the scene light, with it's specific color temperature, on sensitive media with similar RGB filtering (at least spectrally) and set gains/sensitivities on those channels at capture time.
