About 45 percent of illegal immigrants work in the underground economy, thereby avoiding all income and employment taxes. And, because Mexicans send $23 billion a year of their earnings in remittances back to their home country, they pay little sales taxes for purchases of U.S. products. Title IV, Section 413, locks the bill into the Security and Prosperity Partnership of North America, which President Bush agreed to with Mexican President Vicente Fox at Waco, Texas, in 2005.

The Security and Prosperity Partnership, in turn, is locked into the five-year plan spelled out in the Council on Foreign Relations document called "Building a North American Community," which called for massive U.S. foreign aid as part of economic integration. It's no surprise that the Senate immigration bill calls on U.S. taxpayers to "improve the standard of living in Mexico." In addition to the heavy costs that the bill would impose on current U.S. taxpayers, it is truly awesome to contemplate the burden put on future taxpayer when the amnestied immigrants and their many relatives retire and collect Social Security and Medicare. Heritage estimates that the net retirement costs - benefits minus taxes - could be more than $2.5 trillion, which is five times the cost of the Iraq war.

Globalists try to tell us that bringing in more workers will expand and enrich our economy. That's nonsense. If millions of low-skill, low-wage workers could build a country's wealth, Africa and South America would be the richest countries in the world, and obviously they are not.

The influx of tens of millions of low-skill workers, who pay almost no taxes and send $23 billion of their earnings out of the country, will increase U.S. poverty and impose a tremendous burden on U.S. taxpayers. The increased supply of low-skill workers will also depress the wages of low-skill Americans who compete for low-wage jobs.

The terrible costs of the Senate immigration bill's buyout of Mexican poverty is not the legacy we want to leave our children and grandchildren. Because the bill and its advocates never address the issue of costs, it's up to the voters to hold their senators responsible.
