Regulatory capture is THE problem. Contrary to the parent post's claim, the problem is not with our "economic system". It's that, if you're going to regulate something (particularly something as complex as nuclear energy), then you need experts. And the only place to get those experts is from the industry. Generally, those people are naturally going to look at the industry from a certain perspective, one that views the activity of the industry as important, and its status quo as something other than an historical accident.
Until you can find a way to extract human nature from the regulatory process -- and that's even before we start talking about corruption -- you're not going to get anything better.
So sure, the industry tries to push the boundaries, and we should call them out for that. But while doing so, we must also consider how the regulators -- themselves humans -- might do even worse. That side of the equation is too often overlooked.
