Thinking that economy will belly up is not really something new, it is a 3000 year old tradition in humanity because unfortunately finance never lets us down when we expect it to let us down.
Just because we lived the 2008-09 era do not think that it was the first one, in the past thousands of years of humanity there has always been bubbles and there has always been crashes that go beyond everything we see on regular days right now when you live in a decent nation, even the biggest roman empire of the time had hard time paying for food, water and wine the basic things for life in those times. Sure there will be another financial crisis one day, but that doesn't mean we have to do anything different with our lives, because it will happen and it will leave.
