I think the author buried the lede here. My biggest takeaway from the article is that you'd have to be an absolute sucker to work in academia given how poorly you'll be treated. Each person that puts up with this only makes the problem worse, giving at least tacit approval to the status quo. If folks were to start opting out of academia in larger numbers for jobs in private industry, schools would be forced to improv…
Sure, I maybe have the mental faculties to become an engineer. Do I want do so, however? If I go to work in a firm, I need to do what the owner of the firm wants to in exchange for the monetary and other rewards. In academia, you write grant applications and research proposals for something you want to do (or to be practical, something you and you advisor agree on, but usually the opportunities are much larger than "client wants a webshop").
And what I would be doing at a $firm? Building more applications and other products and optimized adverts of products for other people, when majority of my free time I try to avoid unnecessary apps, adverts and consumption of useless products that waste natural resources of our planet for no good reason at all?
Sure, there are some companies who offer opportunities at doing basic research, but a) getting into those jobs you need to be exceptionally exceptional (getting into a PhD program, mere "exceptional" is enough), and b) would I really, really want to work there? I am reasonably sure that I have less ethical dilemmas if I am funded by a government or foundation to do research at a public university than getting a paycheck from $big_name_company, to produce value for $big_name_company.
