you mean letting the markets self-regulate. history has shown time and time again how well that works with recent events such as the BP Gulf oil spill and 2008 banking collapse being perfect examples of it's failure in reality.
government created the corporation and it's their responsibility to control them. self-regulation is purely delusion as history shows regulations were put in place because they were needed. does the love canal or erin brockovich ring a bell to anyone.
if self-regulation was ever going to work it surely wouldn't be in the US. the past 40 years shows how much US large firms care about american citizens, as stagnant wages are proof positive of this disconnect. but of course there was also lots of help from the central bank due to inflation.
It isn't that industry won't self regulate. We just haven't waited long enough for it to happen. Yeah. That's it.
