Per the Washington Post, 1.4% of schoolkids are undocumented.
There are approximately 3.3 million public school teachers in the US. That means 46,200 teaching jobs were created to teach these undocumented children. How many directly supporting jobs does that make? Principals, school secretaries, janitors, cafeteria workers, copier repairmen, etc. Plus the retail jobs created because those 40k+ teachers and the supporting staff have salaries to spend.
This pretty simple analysis is right in lne with the scientific studies that have been done on the economics of illegal immigration.
From FactCheck.org, "The consensus that immigrant workers expand the U.S. economy is broad, and crosses party lines. In 2005, the White House of Republican President George W. Bush remarked on the fact in one of its
annual economic reports to Congress"
"whether they’re legal ... or illegal ... really doesn’t matter for the purpose of answering our question: The truth is that immigrants don’t "take American jobs," according to most economists and others who have studied the issue.
Immigrant workers "create almost as many" jobs as they occupy, "and maybe more," said Madeleine Sumption, policy analyst at the nonpartisan Migration Policy Institute, which is funded by a range of foundations, corporations and international organizations. "They often create the jobs they work in." In addition, "they buy things, and they make the economy bigger," she told us. "
And
"David Griswold, director of the Center for Trade Policy Studies at the libertarian Cato Institute, wrote in an article for Commentary magazine in December:
Griswold: The addition of low-skilled immigrants expands the size of the overall economy, creating higher-wage openings for managers, craftsmen, accountants, and the like. The net result is a greater financial reward and relatively more opportunities for those Americans who finish high school."
And
"And a new study by economist Heidi Shierholz of the Economic Policy Institute — a liberal think tank that has been funded in part by U.S. labor unions – says that:
Shierholz: In the ongoing debate on immigration, there is broad agreement among academic economists that it has a small but positive impact on the wages of native-born workers overall: although new immigrant workers add to the labor supply, they also consume goods and services, which creates more jobs "
A small section of society - likely those without a high school degree - will face increased competition for jobs. At the same time, the numer of jobs will expand.
