> That these staggeringly high numbers (if true) do not necessarily mean doom but "merely" that at some point people will find out that the pensions they have been promised won't be there when they reach retirement. (I.e. what the people in Greece are currently painfully experiencing will eventually hit others, too - one pension cut after the other until little is left.)

Not only Greece; it's the same in Germany. People who have worked their whole life sometimes have a lower pension than they would receive if they would apply for welfare.
