Griffin criticized Trump's strategy of building a strong manufacturing nation.

Ken Griffin, founder of Castle Investment, has increased criticism of the Trump administration's trade policies, stating that tariffs will not bring back manufacturing jobs to the United States as the president envisions. Griffin believes that the United States should leverage its own strengths instead of going against the trend. "He wants to help people regain their dignity, which is a very good idea," Griffin said at an event at the Stanford Graduate School of Business on Friday. "But the dream of creating more manufacturing jobs is not possible." "These jobs will not return to the United States," Griffin said. "And to be clear, when the unemployment rate is at 4%, the U.S. no longer needs to be entangled in this issue." The billionaire had previously stated that the trade war has become "absurd," and he warned that tariff policies are damaging the United States' global image. On Friday, Griffin once again pointed out that the Trump administration's "deal-making" mindset is contrary to the long-term interests of the country.
