What we actually don't need, are southern crop farmers who break laws. I'm for having these farmers prosecuted.
"The Congressional Budget Office reported in 2007 that "the tax revenues that unauthorized immigrants generate for state and local governments do not offset the total cost of services provided to them" but "in aggregate and over the long term, tax revenues of all types generated by immigrants—both legal and unauthorized—exceed the cost of the services they use." Unauthorized immigrants demand goods and services while an estimated 50 to 75 percent pay taxes. Due to cheaper labor, they contribute to lower prices in the industries where they work, such as agriculture, restaurants, and construction
Studies have shown that overall in the long run illegal immigration benefits the country in terms of its general production, but introducing many people in the labor market can lead to income distribution that can tend towards domestic workers and immigrant workers on other occasions. The net short-term impacts of some aspects of illegal immigration can be inconclusive. Though this net effect changes, the number of immigrants crossing the border illegally is less unclear. Aviva Chomsky, a professor at Salem State College, states that "Early studies in California and in the Southwest and in the Southeast...have come to the same conclusions. Immigrants, legal and illegal, are more likely to pay taxes than they are to use public services. Illegal immigrants are not eligible for most public services and live in fear of revealing themselves to government authorities. Households headed by illegal immigrants use less than half the amount of federal services that households headed by documented immigrants or citizens make use of."Professor of Law Francine Lipman writes that the belief that illegal migrants are exploiting the US economy and that they cost more in services than they contribute to the economy is "undeniably false". Lipman asserts that "illegal immigrants actually contribute more to public coffers in taxes than they cost in social services" and "contribute to the U.S. economy through their investments and consumption of goods and services; filling of millions of essential worker positions resulting in subsidiary job creation, increased productivity and lower costs of goods and services; and unrequited contributions to Social Security, Medicare and unemployment insurance." programs."

I'm not saying that illegal immigration is necessarily good, but it is also not the great tragedy talking heads try to make it. Certainly not enough to build a wall which will be damaging to wildlife and absolutely won't stop people from crossing. They will go over, under, and around it. Human and drug traffickers will just find another way to do their business. You can't cover the entire country in an impenetrable bubble.
Then there are the actual numbers on crime. How many illegal immigrants commit crimes compared to the legal population?
