A fair question that deserves a fair answer, despite the sarcastic continuation.
Illegal aliens' labor is directly subsidized by tax dollars for social services - for housing, for medical care, for schools and a host of other services. It's not like they just work here and pay their way, as in the 1900s immigration waves.
By keeping them here, legalizing them and importing more, Bush's plan will increase the burden of taxes that support the welfare industry. The poor don't pay those taxes, the middle class does.
Not when they are employed, to any large degree.
Most are very proud and don't take as much as these numbers that get thrown around indicate.
Also, these numbers do not include the contributions through taxes for goods, services and property taxes through rent.
The numbers on both sides of the issue are stretched and the answer lies in the middle.
The proposal calls for steady employment to qualify. That one statement should defeat most economic fears. With employment requirements the numbers are just wrong. New estimates need to be done, and if/when they are the pucker factor should be eliminated to a great degree if not entirely.
Fable.
Studies generated by think tanks from the Cato Institute, to The National Center For Policy Analysis all agree that immigrants, legal or illegal, have a net positive impact on the economy, and your red herring of the cost to taxpayers of social services rendered to immigrants, is more than balanced by the reduced costs in goods and services to US consumers that come from the lower costs of immigrant labor to American industries.
The American middle class draws large financial benefits from the presence of immigrants.
Here's substantiation for my claim:
"A 1995 Cato Institute study found that illegal immigrants paid approximately 46 percent as much in taxes as American-born citizens, but they received only 38 percent as much from the government. Also, contrary to popular belief, the majority of illegal immigrants were not destitute fence-jumpers but were middle-class tourists or students who overstayed their visas."
"In most respects, immigrants benefit the economy. Today's immigrants appear to be just as entrepreneurial as immigrants of the past. The Alexis de Tocqueville Institute found that the number of Hispanic-owned businesses in Los Angeles County increased 700 percent from 1972-1992 as the Hispanic population increased 200 percent. Stanford University economist Clark Reynolds has stated that if the U.S. economy is to grow at a rate of 3 percent a year, we must find between 5 million and 15 million more workers than can be supplied domestically. Without immigration, the boom times of the 1990s might not have been possible and might not return." --Source
