Trump calls on business students at the university graduation ceremony to go to the workshop and screw bolts, to engage in infrastructure projects everywhere, and to stop thinking every day about getting into finance and making quick money. To be fair, Trump now resembles America's revolutionary mentor; he has accurately pinpointed that American finance has led to the hollowing out of the United States. The real economy is the foundation of a country; without a real economy, we can't even screw in bolts or manufacture ships, planes, and cannons, and thus, its military strength will also decline sharply. On the same day, there were parades in Washington opposing Trump, calling him SJ disease, labeling him as a fascist; in any case, America is now divided and continues to divide.
