THE RECESSION is a wake-up call. Americans need to confront some false gods — free trade, gas guzzlers and Wall Street. In the 1990s, the U.S. launched the World Trade Organization and opened trade with China. Americans were to import more T-shirts and TVs and sell more software and sophisticated services to a world hungry for U.S. know-how. That would move Americans into better paying jobs. Unfortunately, the U.S. welcomed imports with more enthusiasm than China and other developing countries, which kept high tariffs and notorious regulatory barriers to purchases of western products. America’s CEOs and bankers learned how to outsource just about everyone’s job but their own — radiologists and computer engineers joined textile workers among trade-displaced workers.

Since the last recession, imports have jumped nearly $1 trillion, while exports are up only about $650 billion, and the trade deficit now exceeds $700 billion. For most Americans, inflation-adjusted wages have stagnated or fallen, while corporate CEOs and bankers get fat on bonuses and can’t-lose stock options.

China is the biggest problem. It subsidizes foreign purchases of its currency, the yuan, more than $460 billion a year, making Chinese products artificially cheap at Wal-Mart. The U.S. trade gap with the Middle Kingdom has swelled to $250 billion.

Mercantilist growth in China and elsewhere in Asia has pushed up global oil prices nearly five-fold in six years, and the U.S. oil deficit is now $350 billion and rising. To raise our kids, finance a huge trade deficit and generally live beyond our means, Americans borrowed from foreigners. Essentially, the banks wrote ever-more creative mortgages and extended excessive credit card and auto loans. The banks bundled those markers into highly complex bonds, designed to generate fat paydays for loan brokers and bank executives, and sold risk-laden securities to foreign governments, insurance companies, pension funds, and wealthy investors.

When the worst of the bogus bonds collapsed, those backed by risking adjustable rate mortgages, the banks got stuck with billions of yet unsold bonds. Bear Stearns collapsed, and the Federal Reserve lent the banks and Wall Street securities dealers $600 billion against shaky bonds on a 90-day revolving basis. That essentially socializes the banks’ losses on bad bonds.

You have to love Ben Bernanke’s ideas about free trade and capitalism. If you are an autoworker and lose your job to Korean imports, as a good economist, he tells you to go to school and find another job. If you are a New York banker caught paying yourself too much and run short of foreign investors to fleece, he makes you a big loan and lets you hunt for other unwitting clients.

Now foreign investors are nervous about all the money they have lent Americans and the integrity of U.S. banks. They are fleeing dollar investments for euro-denominated securities, gold, oil, and just about anything sounder than the greenback. Americans are forced to cut back, not just on purchases of cheap Chinese coffee makers, but also products made in America. That pushes the economy into recession.

Digging out requires us to cut the trade deficit and clean up Wall Street. Simply, we need to burn less gas, balance commerce with China and live within our means. We can either let the price of gas double to force conservation or accept tougher mileage standards. Fifty miles a gallon by 2020, instead of the 35 currently planned, is achievable, but means more hybrids and lighter vehicles.

As long as China subsidizes the sale of yuan to Wal-Mart and other U.S. importers, the U.S. Treasury should tax dollar-yuan conversions. When China stops manipulating currency markets, the tax would stop. That would reduce imports from and exports to China, create new jobs in the U.S., raise U.S. productivity and workers’ incomes, and reduce the federal deficit.

Ben Bernanke has given the banks a lot and received little in return, except a lot of bad loans. He should condition the Fed’s largess on reforms at the big banks, even if that means lower pay for Wall Street big-wigs. Let the bankers try earning their money. Just like the rest of us.
