The U.S. is an extremely democratic country, where government officials want to communicate with the public and representatives want to let their constituents know what they are doing for them. Because of this, they basically have the desire to be interviewed.
美國是個極民主的國家，官員希望和民眾溝通、議員要讓選民知道他在做什麼，因此基本上都有接受採訪的意願。
