Trump is using the threat of tariffs to improve the United States ability to compete in manufacturing and raw material processing jobs, most notably production of raw materials such as steel, aluminum, oil, and natural gas, and products such as semiconductors, cars, major appliances, lumber, and medicines.
Why? Because he realizes that these raw materials are under our feet and their production lowers costs for Americans while generating very high-paying jobs. Working in oil fields is not easy but those jobs pay $50/hour. The manufacturing jobs are necessary for a nation to survive. Globalists believe that interdependence reduces the desire and profit for war but they have been proven wrong time after time. Also, China has no desire to be a member of the globalist community - their very long-term plan is to subjugate Western nations.
Trump is using the threat of tariffs to improve our status. He did the same thing his first term. The mere threat has caused a massive response and highlighted what is happening with China, Vietnam, etc. abusing the tariff game to benefit themselves at the cost of the United States and her citizens.
Finally, anybody screeching and moaning about Trump's tariff approach is to be completely ignored unless the same individuals voiced their concerns about the loss of millions of jobs in the manufacturing heart of America in Pennsylvania, Ohio, Illinois, Michigan, Missouri, Kentucky, Tennessee, West Virginia, and North Carolina. Why do we think Fentanyl deaths are happening so frequently in a lot of those areas? Because of the booming economies and optimism?
