Nobody is really looking for the culprit of this seemingly huge problem. Why is that? America is quick to load the courts with lawsuits about almost anything, why not the Y2K problem? Some companies are worried that they may be sued if they don't adequately prepare themselves, but nobody's looking for the criminals behind this national crisis. Most of the legislation on the Y2K problem, in fact, is intended to indemnify various groups and head off lawsuits.
The main reason why the people in charge aren't looking for culprits is that it isn't in their best interest to assign blame. In addition, the media doesn't understand the situation well enough to even guess who is to blame. Fortunately, we have no such problems -- so let's point some fingers.
