This is not something new but just a pattern-there is a bullish growth that is covered by the global crisis and sheds excess weight after which the "era" begins again (10-15 years) of another bullish growth and so on in a circle. This is nothing new so words like "If you Don't get Rich now you will stay poor all your life!!"they sound too loud. In the noughties, I think they said that too, and after the 2008 crisis, they said it even louder - but I don't see trillions of homeless people after all these markets drops
The 2008 crisis was directly related to homes foreclosure, the next crisis will probably not affect much real estate (apart from severe drops in certain places). People might not be expelled from their houses, but it is likely that we'll see an increase in misery (alcohol consumption/violence/drug abuse/etc).
