According to Jinshi, the United States is facing a housing affordability crisis, and U.S. Democratic Senator Warren blames the Federal Reserve for the problem. In a letter to Federal Reserve Chairman Powell, Warren expressed shock at how mortgage rates have made a bad situation worse and urged Fed officials to start cutting interest rates. Warren and Democratic Senators John Hickenlooper, Jackie Rosen and Sheldon Whitehouse wrote in the letter urging the Federal Reserve to consider the impact of its interest rate decisions on the real estate market and reverse the situation where many people cannot afford to buy a house due to interest rate hikes.
