These "scarce" skills and requirements are trivially gamed on a regular basis. Large numbers of positions that are eventually filled by H-1Bs don't, in truth, require skills and experience that you simply can't find domestically. Sure, every once in a while you need a nuclear engineer or some other domain expert in a very, very narrow domain, and you may have a genuine shortage of talent. But for general-purpose IT and commodity development, these skill are not in short supply domestically if you're willing to pay market salaries.
