US Treasury Secretary Janet Yellen has warned that the outlook for higher interest rates will make it more challenging to manage federal debt and deficits. Yellen emphasized the need to boost revenue in negotiations with Republican lawmakers to address the growing borrowing needs of the US government. The Federal Reserve's new 'higher for longer' rate stance highlights the increasing concern over the growth of the federal debt. Critics argue that the government's efforts to justify lower interest rates are aimed at artificially inflating assets held by the wealthy, while some believe that inflation data is being manipulated to support these policies. Some have suggested opting out with Bitcoin as a response to these economic challenges.
