When America opened its doors, was this what they expected?

Imagine an immigrant, who supports a wife and 3 kids, coming into this country. He finds a job working in a Pittsburgh factory which hired illegals for jobs that required few special skills. The arrangement suited both sides until an injury on the job sent him to the local emergency room. He suffered permanent disability and now remains in the U.S. to claim compensation. This story is one of many we have heard that represents the faults in our nation's current argument on immigration.
Advocates of open immigration argue that our economy needs immigrants. Who else would do these low-wage jobs? Supporters say immigrants bring skills and capital that expand our economy. I have to disagree with these claims. America does not have a vast labor shortage that requires tidal waves of low-wage immigrants to alleviate. Unemployment all over this country is high. Immigrants, some of them illegal, are forcing out native workers. Some of these immigrants are uneducated and unskilled forcing businesses to crumble. They are taking jobs away from families that have lived here all their lives. Is this the American dream or the American nightmare?
These workers add little to our economy and come at a great cost. Immigration can only pay off if America reshapes it's policies and hires workers that they truly need. This country needs to exclude the ones that cost more than they contribute. The flood of immigrants, both legal and illegal, has caused a mismatch between uneducated populations and American economy. U.S. sentiment has risen to an all-time high to slow and even stop completely the overflow of our borders. Mexican immigrants can earn seven to ten times more in the United States as at home. Nearly two-thirds of them are high school dropouts. We have our own dropouts that need to find low-skilled and low-pay work. They are pushing our native workers out of jobs and into the unemployment lines. They are even pushing American products off the grocery shelves. Many grocery stores are now stocking up entire aisles of Mexican food products. What's next? Will Americans all be required to speak Spanish to gain employment?
Consequently, the waves of immigration continue, the overflow of those competing for low-skilled labor will continue to make the progress of our economy impossible. In fact, as Mexican immigrants flood our country, many of their children follow in their parent's footsteps in that 60% dropout of high school and then perform low-wage work. Immigration has certainly damaged the fabric of our economy and our schools. America has opened its doors. Was this the result the expected? It is my hope and dream, that we will someday wake up from this recurring nightmare.
