One of the drawbacks to our capitalist, business-focused system, is that we privatize profits, but publicize risks. That is to say, when people make a profit from doing something useful, that profit generally goes to those people / that corporation. But when people cause damage in pursuit of profit, those damages generally get paid for out of the public pocket, due to exemptions, loopholes, insurance, court delays, bankruptcies, or just general cheating. The impact of mistakes (or malice) gets absorbed by everyone.
A fine look at the phenomenon and a variety of examples here:

Tightly coupled to this is the idea that Shit Happens. Mistakes Are Made. Sooner Or Later, Boom.
If someone assures you that something will never leak, that idiot-proof systems will never fail, that everyone is well-trained in all the proper processes, that nobody will ever be negligent or tired or drunk or complaisant or distracted, that nothing can ever, possibly, go wrong here — then they are either Pollyannaesque optimists, or are trying to take advantage of you, most likely in order to shift the risk of their operations to the public who will have to absorb the costs of clean-up and economic damage to people's livelihoods.
