The problem is that those in charge disagree with that. When I brought this up after a recent policy change at my department to not allow hiring own PhDs as postdocs (because they should go to another lab, as this is what your CV is expected to look like), I was told that a Phd programme should not be seen as a path towards an academic research career. In contrast, I was told that it is very important to train as many PhD students as possible, that all don't stay in academia, so they can bring scientific thinking to all areas of society. Unfortunately, starting PhD students, of which 99% do this explicitly to do research, are not aware of this, and neither do PhD programmes offer any specific training for a non-academic career.
One solution would be to push more people towards MS degrees, which should be no more than 2-3 years in duration and focused on gaining skills and experience valuable in the private sector.
