Yes, this will hurt the U.S. economy because it gives China the ability to change the law themselves. The US has no say in this deal anymore. China can come up with their own plans to help their economy. It gives them all of the power when importing and exporting goods.
Withdrawing the U.S. from the Trans-Pacific Partnership is destined to hurt the U.S. economy. We rely on trade and to withdraw from partnerships that benefit us we only hurt ourselves. I think that Donald Trump has a mis-aligned perception of what foreign trade is and the effects of our trade deals and partnerships.
Free trade is good for everyone. Free trade is a win-win, making both countries richer. Withdrawing from the Trans-Pacific Partnership will hurt the United States economy. America should be a leader in the Global economy--embracing trade and promoting more cooperation among nations. Withdrawing from the world and trade agreements will hurt the economy.
Trump is a wise business person. The rest of the country should trust his leadership a little bit. Trump wants to make sure that businesses keep their jobs in the United States. He wants to break down regulations that make it impossible for people to do business. This is a good decision.
