It is a fallacy that land and house prices always rise. If that was the case then there is no need for anyone to work, let us all buy land and houses. Some people believe if a land is 1 crore this year, next year will be 2 crores and it goes on like that. This is total rubbish!. 
Greed always backfires on the greedy. USA is a strong country, she has many ways and means to tackle her monetary issues. Who will help Nepal and India if there is an economic collapse?. The greedy people have taken even the middle class people for a ride. But that should end soon hopefully.
