What's worse is that in most of these fields, you don't really even start working until after your PhD.
4 years is going to be a long time to underfund what's basically 4 entire classes of researchers coming out of Doctorate programs. It might take decades to recover our research programs.
If a private lab needs a chemist or biologist for say, quality assurance, one of the most common jobs in the field, then privates prefer fresh graduates:
- they cost much less
- even if the PhD would be fine with the pay, he/she will still be skipped over a fresh graduate because the person is over qualified and will jump to something more related to his/her field as soon as possible.
Thus these people's CV are genuinely worse for anything unrelated to their skill set.
Depends on the market, which is true for any field. In places where there's a lot of technical work to be done, employers can hire PhD's and will do so if there's a local supply.
