Profs get patent royalty. Industries fosnat lay royalty. Profs gets salary from the grants salary apart from their annual salary. Industry doesn’t give you shit from the grants. For example, Profs apply for grants ranging from 200 K to few million and they can add salary as a part of the grant. Bascially its double salary. It won’t happen in Industry. Profs can consult, start a company, and still be employed in a University. Industry is just one work. Industry has infinite flow of money but you are not getting a lot from it. As a profs, one gets salary, grants, patent royalty, start upequity. In other words, in an Industry a researcher can get 300 K and will work for 12 months, but a Researcher in a University will get 150 K to 200 K, extra salary from Grants, royalty and just work for 8 months. One downside is Professorship is a boring job.
