I just recently did some playing around in insights search by Google and found an interesting change in the mindset of people. After 09.2009 the trend in saving money and credits crossed and changed. While befor the crash people tend to be more interested in credits and loans in germany they were now more cautious and looked for saving their money.
If you then compare the situation with the market in the USA you really the drama. After the same switch from loans to savings the market completely shifted again and rose dramatically upwards. Like a hypecurve credits as a topperformer pulled saving behind to a high frequence/volume in search before both plummed down in 2011.
