At a university graduation ceremony, U.S. President Trump advised business students to work in factories and workshops, suggesting they "lay bricks" instead of constantly thinking about financial speculation. He told business students not to use their talents solely for financial speculation, but to apply their learned and mastered skills in America's new factories, workshops, shipyards, and even in the city constructions rising across the country. He emphasized making tangible efforts like forging steel and pouring concrete, rather than just building a strong investment portfolio.
