Immigration to save the economy?

I think Thomas Friedman had a good point in his Wednesday article. Now is not the time to go protectionist.

Loosening immigration restrictions, for example, would bring to America some helpful things: home buyers (we need someone to buy up the bank-owned homes) and innovators.

Here's how he starts his article:

Leave it to a brainy Indian to come up with the cheapest and surest way to stimulate our economy: immigration.

“All you need to do is grant visas to two million Indians, Chinese and Koreans,” said Shekhar Gupta, editor of The Indian Express newspaper. “We will buy up all the subprime homes. We will work 18 hours a day to pay for them. We will immediately improve your savings rate — no Indian bank today has more than 2 percent nonperforming loans because not paying your mortgage is considered shameful here. And we will start new companies to create our own jobs and jobs for more Americans.” 

He later adds:

According to research by Vivek Wadhwa, a senior research associate at the Labor and Worklife Program at Harvard Law School, more than half of Silicon Valley start-ups were founded by immigrants over the last decade. These immigrant-founded tech companies employed 450,000 workers and had sales of $52 billion in 2005, said Wadhwa in an essay published this week on BusinessWeek.com.
