The Globe and Mail reports in its Friday, May 19, edition that Fairfax Financial Holdings boss Prem Watsa has some advice for U.S. President Donald Trump, "Stop using that Twitter account." A Bloomberg dispatch to The Globe reports that Mr. Watsa says, "The problem with Mr. Trump is he's incorrigible." Mr. Watsa says Mr. Trump should "just be quiet." Mr. Watsa says that, while he worries about Mr. Trump, he admires his policy goals and the people he has chosen for top roles in the administration, such as Treasury Secretary Steve Mnuchin and Commerce Secretary Wilbur Ross. Mr. Watsa stands by his bullish stance on the U.S. economy. "We still haven't changed our minds that the United States is going to have significant growth. But it will be up and down, it won't be in a straight line." If Mr. Trump is able to fulfill his promises to slash the corporate tax rate to 15 per cent from 35 per cent, roll back burdensome regulations on business and unleash spending on infrastructure projects, then "we could be in for a long period of growth." He says: "When the U.S. does well, the rest of the world does well. We certainly do well in Canada."
