JPMorgan CEO Jamie Dimon has dismissed Canadian Prime Minister Mark Carney’s call for middle powers to unite, calling it a “fantasy.” Dimon pointed to Europe’s economic struggles as an example of cooperation’s limitations, citing high taxes and regulation. He emphasized that attractive business environments are crucial for growth, contrasting Europe’s declining competitiveness with the U.S. market. Dimon also reassured investors about America’s investment appeal, noting China’s evolving global approach.
