You know that an economic issue has jumped the shark when the New York Times's op-editoraliste Maureen Dowd (MoDo) devotes her Sunday column to it. What's unleashed MoDo's moxie is how Sovereign Wealth Funds (SWFs) -- those government investment funds estimated to control between $2 trillion and $15 trillion -- are buying up chunks of the U.S. banking system.

The problem against which MoDo rails is that thanks to the policies of George W. Bush, the price of oil has quadrupled and the dollar has plummeted -- thus putting the U.S. at the mercy of those Arabian SWFs whose owners he groveled to this week to lower the price of oil. And while W. was grovelling, so were the CEOs of Citigroup Inc. (NYSE: C) and Merrill Lynch & Co. (NYSE: MER) -- seeking capital to shore up their Collateralized Debt Obligation (CDO)-tarnished balance sheets. MoDo is right that with Bush's $2.4 trillion worth of wars and $1.3 trillion worth of tax cuts, the U.S. has gone from being the world's creditor to its debtor.

But another New York Times article sheds more light on the phenomenon of foreign investment in the U.S. -- suggesting that with their $414 billion worth of 2007 purchases in the U.S., foreign investors, including SWFs, spent a record amount of money buying up the U.S. last year -- up 90% from 2006. The Times suggests that this foreign investment comes in different forms -- some of which are beneficial. How so?

The New York Times [registration] reports that the Carlyle Group and the NASDAQ Stock Market, Inc. (NASDAQ: NDAQ) are selling out to one of the countries -- United Arab Emirates -- from which two 9/11 hijackers -- Marwan al-Shehhi and Fayez Benihammad -- hailed.

Specifically, the government of Abu Dhabi, United Arab Emirates' capital, will buy 20% of Carlyle Group, valuing it at $20 billion. While yesterday, NASDAQ announced that is was selling 19.9% of itself to Borse Dubai, the Dubai government-controlled exchange.

But not a peep of protest is emerging from the White House. And why should it protest? This is the decade where it's better to be a barrel of oil -- or a country that sits on oil -- than to be an American. After all, the price of oil is up 242% to a record $82 a barrel since its January 2001 price of $24 a barrel. Meanwhile, since 2001, the median family income adjusted for inflation has stagnated. Bernanke's bailout has slashed the dollar to record low levels against the Euro -- and since oil is traded in dollars -- that means people who drive will be paying more than ever.
