I disagree. "Benefit society" means something that can't be defined or tracked so easily. And consumer behavior is heavily biased by things that aren't optimized to benefit society. I have in mind this book, Hooked by Nir Eyal: https://www.nirandfar.com/hooked/

We should try our best to improve our society. Sometimes that will mean doing things that are economically inefficient. Your example of Stanford professor Nir Eyal is an excellent illustration: by advising corporate managers and product designers how to fulfill their role in our economic system more efficiently, Nir Eyal made our society worse.

We should expect more from our elite professors. Nir Eyal should've known better than to make a career out of studying how deliberately to addict users. But we should also expect our professors, politicians and policymakers to understand the basics of our economic system and to understand when a proposed change to our society sounds good or feels good, but has severe adverse effects on economic efficiency that outweigh the societal benefits. Those aren't the only proposed changes we should avoid, but they form an important class of them.
