Krugman, DeLong, Baker: 'Exploit the Tired, Poor, Huddled Masses'?

The New York Times has a story that let's out un gato del saco regarding the solvency of Social Security:

While it has been evident for years that illegal immigrants pay a variety of taxes, the extent of their contributions to Social Security is striking: the money added up to about 10 percent of last year's surplus - the difference between what the system currently receives in payroll taxes and what it doles out in pension benefits. Moreover, the money paid by illegal workers and their employers is factored into all the Social Security Administration's projections.

Illegal immigration, Marcelo Suárez-Orozco, co-director of immigration studies at New York University, noted sardonically, could provide "the fastest way to shore up the long-term finances of Social Security."

....Starting in the late 1980's, the Social Security Administration received a flood of W-2 earnings reports with incorrect - sometimes simply fictitious - Social Security numbers. It stashed them in what it calls the "earnings suspense file" in the hope that someday it would figure out whom they belonged to.

The file has been mushrooming ever since: $189 billion worth of wages ended up recorded in the suspense file over the 1990's, two and a half times the amount of the 1980's.

In the current decade, the file is growing, on average, by more than $50 billion a year, generating $6 billion to $7 billion in Social Security tax revenue and about $1.5 billion in Medicare taxes.

....Using data from the Census Bureau's current population survey, Steven Camarota, director of research at the Center for Immigration Studies, an advocacy group in Washington that favors more limits on immigration, estimated that 3.8 million households headed by illegal immigrants generated $6.4 billion in Social Security taxes in 2002.

A comparative handful of former illegal immigrant workers who have obtained legal residence have been able to accredit their previous earnings to their new legal Social Security numbers. Mr. Camarota is among those opposed to granting a broad amnesty to illegal immigrants, arguing that, among other things, they might claim Social Security benefits and put further financial stress on the system.

Now, let's revisit that weaselly paper being circulated by our Trinity of economists:

In most futures we can think of, the world in 2050 or 2100 contains a great many people outside the U.S. whose productivity would be amplified if they were able to move to the U.S., and so we suspect that for at least the next century immigration will play as large a role in America's future than it has in the past.

Forgetting to add: And we can rob them blind!
