This, or some more or less tragic version of it, is a common story in the academe.
As such, I understand those who seek a PhD with the intention to pursue a career other than as a traditional academic. If only a small fraction of those with the degree land full time faculty positions, while the remainder are left scrounging for part time work, then a reasonable response is to generate alternative career paths for the degree. Less dramatically, some PhD candidates simply discover that the traditional work of an academic or the environment in which it is done does not suit their tastes.
In either case it makes sense that institutions develop programs that facilitate the pursuit of alternative, non-traditional career paths. In this way the degree is not retired and graduates enjoy productive, fulfilling work lives - and love lives.
There is, however, a problem with the alt-ac response. Ironically, the response utterly depends upon the traditional academic career it is meant to avoid and so ultimately reintroduces the very employment perils of the PhD it is meant to avoid.
