Well, the question is: how much of the problem is explained by the "pipeline" theory. If a company hires x%, and there are y% graduates, then we have a pipeline problem if x=y, or is close to y. If x is much smaller than y, then the pipeline doesn't explain the whole problem. I am not taking a stance on the pipeline issue in the general case. It may or may not be a problem for particular companies on a case by case basis.
