Remember, America's current generation of CEOs cannot MAKE anything except deals. They are not great geniuses like Edison or Ford. They don't understand how their products work or how they are made. They cannot really DO anything, but, by God, they can cut costs. That is their specialty.
One place they cut is workplace safety, product safety, process safety, etc. They cut corners and get huge bonuses for it. If a particular CEO won't cut those corners, then his board of directors will find someone who will. When a CEO says, "Get it done. I don't care how you do it, just get it done," that is when corners are cut.
We have to realize that corporations have no values except accounting values. By our nutty corporate laws, a corporation is legally a person. If the same laws that applied to real people applied to corporations, then we would have it institutionalized in an asylum. The corporation is a sociopath. It has no human values and cares nothing for the welfare and happiness of others. The corporation is an idiot-savant that can do one thing brilliantly: deliver product to market. It is incompetent or malicious when performing every other task. Corporations cook the books, pollute, cut corners, bribe elected officials, and ignore safety regulations whenever and wherever possible. Corporations employ child labor and slave labor where they can. The corporation is a pathological liar. Corporations lie to investors, lie to consumers, lie to Congress, lie to regulators, and lie about how much oil is leaking from one of its wells.
