I think we've seen time and time again that self-regulation of the industry doesn't work and that businesses will gladly fuck over society if they can get away with it and make more money. Usually that behavior is even defended with saying "Well, it's not their responsibility to solve society's issues. They are there to make money."

Barring nationalization of an industry, heavy regulation and/or taxation/subsidizing are the only ways to reliably protect the interests of society. If some businesses get killed in the process, so be it.
