Alpine Structure Conundrum

Hi Nordic Gurus, One question. If structure is so important on the base of nordic skis, why don't we hear anything or read anything about structure on Alpine race skis. Is it just that we need structure at lower speeds, and beyound those slower nordic speeds they don't bother? Or, is it that it's so obvious alpine race waxer don't need to talk about it? I bought an expensive structure tool about 6 years ago because of all the hype about how structure can make your skis (not you) faster. But since then, I can't find a single person I ski with that uses a structure tool.
