Is it good, or is it a scam for lazy government?

An article in a newspaper I was reading today states that at a County Fair in Southern California, there is a person employing foreign workers on guest visas. Now we have the HIGHEST rates of unemployment in the country, and that is happening!!?? Americans can't easily travel to another country to get jobs, WHY CAN FOREIGNERS come here? Because they will do jobs we won't do? HEY SENATORS and CONGRESSMEN, Ever ask a homeless person what they would do for a job (given that they are sane of course??? This H-1B Visa Scam (as I call it), is, as they say, another way the rich get richer and the poor get poorer.
