Historically, reactions to prevent the last major crisis from happening again generally contribute to the next, which is invariably very different.
There's an article
here but it's a bit long.
The old tricks aren't the problem. Housing bubbles come and go with little harm as a rule, its panic that spreads them into contagious global crap-outs.
But the array of new and quite bad things that have happened since the last crash means something else will surely break sooner or later. After the even it will be blindingly obvious to us all what was the cause, but prior to it nobody can really say for sure. Perhaps China's malinvestments will collapse. Or money flows to entire emerging markets will cease (as banks stop dealing with them for fear of US money laundering prosecutions - which is happening at an alarming rate); The US Congress might force a real default, probably by accident; too-big-to-fail regulations may cut global banks into bite sized nationally bound chunks and force up financing costs globally while causing banks to fail more easily - and counterproductively increasing the costs of bailouts.... there's plenty of other options.
