Internal audits at a financial company, for example, are done because of government regulations, not because of the companies risk averseness. That same averseness also applies to safety mechanisms in at-risk businesses.

It is far more profitable for a system to be safe than it is for it to be completely free. Unsafe conditions or worse an employee death causes massive rippling effects throughout the rest of the workforce. Look at Massey Energy. They ignored safety to get it done faster and better, they ignored their own internal bureacracy. And it has effectively killed them as a company.
is demonstrably untrue across a wide variety of industries. Coming from a town where mining and smelting are our largest industries followed by logging, management always has to find the optimum balance between the costs of injuries and the costs of the safety measures put in place to prevent those injuries.
It is not more profitable for the system to be safe, and it is not more profitable for the system to be completely free. The most profit comes in the equilibrium between the two costs.
Regulation shifts that equilibrium point farther along the 'safety cost' curve without necessarily a reduction in injury costs. I'll take Walmart as an example. Imagine the Government determined that too many people were hurt lifting 20lb items off of the top shelf. So they regulate that 20lb items can only be lifted off using automated lifting equipment. Now, the costs associated with providing that equipment and the training for that equipment far outweigh the costs associated with possible injuries from doing those lifts. The company has been forced out of their cost equilibrium. This is an extreme example, of course, but it isn't too far from what actually happens in business today. HOWEVER - because this regulation is forced on all companies competing in that industry, no one particular company loses more than another out of that change assuming that they are able to shift their costs to the new equilibrium. Small companies often have trouble doing that.
If the CEO of ExxonMobil were to walk into Washington today and start running things, he would over-regulate to the point that smaller companies wouldn't be able to recover those costs and would have to go out of business. This is actually happening today and is a lot of the impetus for self-regulation in industries. And a big reason why small businesses have huge problems with the way regulations are put forth. Speaking from personal industry experience, financial reporting standards like IFRS were introduced by large financial corporations and represent HUGE costs to smaller organizations who don't have the personnel or the knowledge to deal with the increased scutiny, even if in the end, the extra scrutiny only represents what many would call 'financial theatrics'.
