Bad example in my honest opinion: Merkel made me believe it's the "worst case scenario" kind of thing - same reason there shouldn't be capital punishment. If you can't afford to pay the price in the worst case scenario you shouldn't take the risk.

That being said, I believe failures and mistakes are simply part of our lives. I would turn the other way and run when someone says that he found the perfect system, in which there are no losses failures and problems. You are always limited by what you don't know you don't know.
