Another idea to retain or hire faculty: let them have dual enrollment at tech companies and universities. Not sure if this is a good idea, or if it works. But I'd certainly be interested in studying the outcomes of it. Potentially could cause a conflict of interest in motivation of academic research vs industry driven research to profit the company, or even be used as a way to fast-track students to said company. Not that these things are inherently bad, but such decisions could have undesired outcomes for the universities that do this. But could be an idea worth exploring. Or, universities could become more competitive with salaries.
