Paul Krugman: Dreamers, Liars and Bad Economics

"Trump and company tell a lot of lies about economics":

Dreamers, Liars and Bad Economics, by Paul Krugman, NY Times: Does it matter that Jeff Sessions, the attorney general, tried to justify Donald Trump’s immigration cruelty with junk economics?

It’s definitely not the main issue. Trump’s decision to rescind the Deferred Action for Childhood Arrivals policy is, above all else, immoral. The 800,000 beneficiaries of DACA — the so-called Dreamers — have done nothing wrong; they came to the United States illegally, but not of their own volition, because they were children at the time.

They are, according to all available data, an exemplary segment of our population: hard-working young people, many seeking to improve themselves through higher education. They’re committed to the values of their home — because America is their home.

To yank the rug out from under the Dreamers ... is a cruel betrayal. ...

Still, Sessions chose to put economics front and center in his statement, declaring that DACA, which allows the Dreamers to work legally, has “denied jobs to hundreds of thousands of Americans by allowing those same jobs to go to illegal aliens.” That’s just false...

Trump and company tell a lot of lies about economics (and everything else). ...

The truth is that letting the Dreamers work legally helps the U.S. economy; pushing them out or into the shadows is bad for everyone except racists.

To understand why, you need to realize that America, like other advanced economies, is facing a double-barreled demographic challenge thanks to declining fertility.

On one side, an aging population means fewer workers paying taxes to support Social Security and Medicare. Demography is the main reason long-run forecasts suggest problems for Social Security, and an important reason for concerns about Medicare. Driving out young workers who will pay into the system for many decades is a way to make these problems worse.

On the other side, declining growth in the working-age population reduces the returns to private investment, increasing the risk of prolonged slumps like the one that followed the 2008 financial crisis.

It’s not an accident that Japan, which has low fertility and is deeply hostile to immigration, began experiencing persistent deflation and stagnation a decade before the rest of the world. Destroying DACA makes America more like Japan. Why would we want to do that? ...

In short, letting Dreamers work is all economic upside for the rest of our nation, with no downside unless you have something against people with brown skin and Hispanic surnames. Which is, of course, what this is all really about.
