Why is SquareEnix deliberately REFUSING to make a final mix in English of Kingdom Hearts?

I realize that SquareEnix is their own company and they can do whatever they want to with their games but it just doesn't seem to make very much sense. I mean, they would get more money, I would believe. It just seems that they want to get everyone to learn Japanese OR ELSE NO PLAYING FINAL MIX MWAHAHAHA!!!

But really, does anyone know the reason?

(I'm sure this question has been asked multiple times already... )
