Washington is the seat of power in America since it is the capital city. Therefore, it houses major buildings such as the White House, the Capitol, and the Supreme Court. At the same time, Washington is also the hub for global development finance, since it headquarters both the International Monetary Fund (IMF) and the World Bank. Naturally, this also means that government contractors play a crucial role in the Washington economy. This city is also one of the most expensive places to live in America.
