The outside world has an influence with a government only when it feels like it is a participant, particularly when pressure comes from trading partners it cannot afford to lose. Some union members may be priced out of the market when they have to compete with Chinese labor. But the Chinese have an insatiable appetite for U.S. goods, so Chinese wealth created by increased trade means more job opportunities for Americans in other industries. Temporary job displacement isn't necessarily bad if it results in lower consumer prices and increased wealth for both trade partners. The world is a global marketplace.
China has the largest population of any country.
Its economy already is growing rapidly, and it will expand much faster when it joins the World Trade Organization. Congress can either allow U.S. citizens to benefit from the explosion of Chinese trade, as Clinton and the Republicans want, or it can cede that prosperity to other countries instead, as Gephardt and the union bosses who are his allies prefer.
