- Academics contribute to the society by creating valuable knowledge
- Academics help students to improve their lives through education.
Having spent in academia many years I see how flawed these arguments are.
First of all, academia is no better than any other field. In fact, it can be much worse in terms of positive societal impact compared to other fields. While 1% of academics do push the boundaries of knowledge and help the society to solve its nascent problems, 99% are engaged in useless and trivial research and irrelevant teaching. Moreover, many high-impact inventions come from outside of academia: aspirin (Bayer), cars (Ford), copiers (Xerox), etc. Heck, even if we are talking about purely intellectual products, such as influential books, we see that many of those books were written by people without PhDs. So I just don't see how academia is somehow better in terms of its contribution to the society.
Secondly, professors are not providing education for free. Schools charge ridiculous amounts for tuition. The reason that many educators generally receive less money compared to the industry is due to the fact that education system is often very wasteful and has to pay less in order to compensate for the waste. Moreover, students often discover that the time and money spent is largely a waste and does not lead to any better lifestyle.
So, again, I don't see how the act of committing one's life to educating the young is more heroic than, let's say, committing your life to providing people with good food. Being sympathetic to a struggling academic is like being sympathetic to a store owner who doesn't sell anything that people are willing to buy.
