evidence shows that the new immigrants behave in positive ways similar to their predecessors. They are family oriented, they value education, and their children are learning English. Overtime, they are intermarrying among growing numbers of other ethnic groups. They are people of faith. They are energetic, looking to move up in life through better jobs–they work hard and for long hours.

often take jobs many Americans simply no longer wish to do. By and large the most recent surge of immigrants is made up of people who are young and mobile, and who work in the least desired sectors of the . economy such as agriculture and service industries for relatively low pay. Today, only about 10 percent of white males leave high school, and high school graduates won’t take the menial jobs that many immigrants are happy to take on. So for the most part, the new immigrants and native Americans are not competing for the same jobs. Even when they do compete more directly with low-skilled workers, the job preference is different. Immigrants find work in agriculture, while less educated natives often end up in manufacturing.

Blaine's starvation stunt was a spectacle to the British. Families turned out en masse at weekends to see how his hunger strike was going. Some normal-size people turned up to mock, throwing eggs, cooking food and even trying to cut off the water supply to the hungry American. The reason for such behavior is that the notion of somebody giving up food for 44 days is unthinkable for the British and there are so few starving Americans in the world, which makes his self-imposed ordeal appear ludicrously self-indulgent.
