Burned houses and ruins make about 40 % of the city of Detroit. There are over 33,000 unused or abandoned buildings here right now. Dave Bing, the Mayor of Detroit, is planning to demolish about 10,000 homes in the next three years. He got the money from the Federal Budget for this purpose. Actually, the economical level of life in this American city is not very high. The unemployment rate here is 50 %, according to Mr. Bing, while this number is approximately 10 % across the USA.
