I've said it before, and I'll say it now. NO MORE IMMIGRATION FOR 10 YEARS. Shut it down. Lets catch our breath. Let's through out those who don't belong here and produce NOTHING for the country.
Better idea: let's deport any lazy, unproductive Americans, even if born here, and replace them with hardworking immigrants who appreciate the opportunity. We don't need people who don't apply themselves in school, are unwilling or unable to train in useful skills, or expect to be handed good-paying but low-skilled "jobs" just because they are born here. There are plenty of people outside the USA who have developed the necessary skills to drive economic growth, and would love to apply them here.
