I find it hard to understand this administrative mechanism in the United States. Since the president has the power to appoint and dismiss the chairman of the Federal Reserve, why does the chairman still dare not to listen to the president?

Trump: The result of the new Federal Reserve chairman appointment will be announced soon.

U.S. President Trump stated in an interview with reporters that the result of the appointment of the next Federal Reserve chairman will be announced soon, and he has a fairly clear idea about the candidate. He added that a good Federal Reserve chairman will lower interest rates. Moreover, when asked whether he would consider cutting government contracts held by Musk, Trump stated that he would consider everything. He mentioned that he has no plans to talk with Musk and hopes he succeeds at Tesla.$TRUMP
