Immigrants working the fields

In both California and Texas, agricultural employers have been hiring illegal immigrants since the World War era and before. Nowadays farmers depend on immigrants to harvest the fields, because most Americans have moved away from agriculture. The only ones farmers can rely on now are the immigrants. The immigrants come here for a better life, because back where they are from there is no hope for a greater future. Many immigrants come from far and there journey here is rough. It's expensive for workers to come to the U.S. Immigrants pay thousands of dollars for border experts to bring them here, and the walk here is tiring and dangerous.
