Mazda vs.Others. Question?

Ok first off I am a die hard Mazda fan period. Just to clear things up I am an American white man. Now my question is simple, how come Mazda doesn't come out with a car (mainly the rx8) that can compete with the nissan gtr or the toyota supra ??? Mazda has the money and the know how. Just look at the 1991 Le-mans. And how the very next year they kicked Mazda out because (for lack of better terms) their engines were too "small". To me I think alot of people and companies got really scared. However, we all know that Mazda could make a super car like the nissan gtr that is still a daily driver and still compete with all the big boys in Japan and most of America. So why don't they ???... Please don't respond with some uneducated answer cause you drive a nissan or supra, because for a little $$$ you could get a Rx7 to run by you.
