What does Wall Street in America mean?

Wall Street is the name of a street extending from Broadway to the East River in southern Manhattan, new york. It is only a third of a mile long and only 1 1 meter wide. It's a transliteration of the English word "Wall Street". This street is narrow and short, only seven blocks from Broadway to Donghe, but it is famous as "the financial center of America". Managers of banks, insurance, shipping, railways and other companies set up by Morgan chaebol, Rockefeller Oil King and DuPont Consortium are all concentrated here. The famous new york Stock Exchange is also here. It is still the headquarters of several major exchanges, such as Nasdaq, American Stock Exchange and new york Stock Exchange. The word "Wall Street" has now surpassed the street itself and become synonymous with nearby areas. It can also refer to financial markets and financial institutions that have an impact on the entire American economy.
