As President, I have seen the transformative power of trade up close. I've been to a Caterpillar factory in East Peoria, Illinois, where thousands of good-paying American jobs are supported by exports. I've walked the grounds of a trade fair in Ghana, where I met women who support their families by exporting handmade dresses and jewelry. I've spoken with a farmer in Guatemala who decided to grow high-value crops he could sell overseas -- and helped create more than 1,000 jobs.
