Likewise to academia and professional science, by the way: 70% of all faculty are adjuncts, and most working scientists don&#x27;t even become adjunct faculty.  Thus, almost everyone working in science on a daily basis is either a grad-student or post-doc (paid low wages because they&#x27;re theoretically a trainee for a position they&#x27;ll never really get) or an adjunct faculty member (used to do the teaching labor the administration wants done but which would distract real professors from frantically applying for grants).<p>Oh, and advancement runs on a feudal hierarchy[1].<p>[1] <a href="http:&#x2F;&#x2F;advances.sciencemag.org&#x2F;content&#x2F;1&#x2F;1&#x2F;e1400005" rel="nofollow">http:&#x2F;&#x2F;advances.sciencemag.org&#x2F;content&#x2F;1&#x2F;1&#x2F;e1400005</a>
