I think this works by providing a second application for older chip manufacturing facilities. For SD chip designs, speed and size effectively do not matter (the controller will matter a hell of a lot more for final speed than actual storage chips speed). So they're using the chip fabs that everyone else is abandoning.
As a second bonus, even on old systems SD card circuits are relatively small (compared to a 5-60" LCD they certainly are). Wafers are round and old wafers are used to manufacture LCD displays, so small chips can be placed around them in the manufacturing process and get really good economics by having lots of manufacturing options.
So same reasons displays are getting cheap, except they're even better. So the race to the bottom is happening pretty fast for SD cards.
Not entirely sure about this. Might be entirely wrong, but I'm not sure how to confirm this.
