'Subprime mortgages'.

subprime means in some way below prime, not at the top level. From around 2005, the word subprime started to feature with increasing frequency in the media. Subprime mortgages is easy credit. The banks and building societies of lending money to people with lower incomes or dubious credit ratings. The meaning of the word reversed and the ‘subprime’ part came to describe the borrowers themselves. Subprime mortgages are now firmly established as one of the ‘bad guys’ in the story of the credit crunch, and it seems that subprime will from now on always be associated with collapsing banks and tumbling stock markets.

I saw documentary of Subprime mortgages, so I knew many American people hed debt.
It’s serious a problem. This the became problem of the world because American is influence . So I thought the problem that must be solved as soon as possible. This problem is the wrong idea. I don't know very well, but I hope they will have solution one's wishful thinkig.
