How did the Dow break 10,000 when the rest of the economy is in the toilet?

1. Corporate earnings are up — mainly because companies have been cutting costs. Payrolls comprise 70 percent of most companies’ costs, which means companies have been slashing jobs. In the end, this is a self-defeating strategy. If workers don’t have jobs or are afraid of losing them, they won’t buy, and company profits will disappear.

2. Federal borrowing has filled the gap that consumers and businesses created when the latter began to reduce their debt. Federal debt, in other words, has kept the economy from tanking. Can’t keep up forever, though.

3. With such horrid employment numbers, Wall Street figures the Fed will keep interest rates low for some time, and continue to flood the economy with money. That’s good news for the Street because it means money stays cheap — and with cheap money the Street can make lots of bets on almost everything under the sun and moon. As a result, the Street’s earnings are way up. But this, too, is temporary. At some point the Fed is going to worry about inflation and a falling dollar.

4. Investors of all stripes want to get in early and ride the wave. Pension funds, mutual funds, and other institutional investors figure the bull market has more oomph in it because, well, other investors will jump in. Think Ponzi scheme. Nice for now, but watch out if you’re one of the last in.

In other words, this is all temporary fluff, folks. Anyone who hasn’t learned by now that there’s almost no relationship between the Dow and the real economy deserves to lose his or her shirt in the Wall Street casino.

In his Saturday radio address, President Obama acknowledged the White House is exploring “additional options to promote job creation.” It’s about time. This is the worst job market in seventy years — including the longest duration of steep job losses.

If anyone had any doubt that something far more dramatic must be done, listen to former Federal Reserve Chairman Alan Greenspan. He warned Sunday against further stimulus because “we are in a recovery, and I think it would be a mistake to say the September numbers alter that significantly.” Greenspan has turned into an inverse soothsayer. After his cataclysmic error about where the economy was headed before the meltdown, his views about the future should be carefully noted as being the exact opposite of what’s likely to be in store.

The economy may be in a technical recovery but this is not a real recovery and the “green shoots” or “positive signs” that Wall Street cheerleaders love to shout about are phantoms of their ever-optimistic imaginations. The stimulus is working but it is far from adequate. Before the stimulus, we were losing more than 500,000 jobs a month. Now that 40 percent of the stimulus has been spent, we are losing more than 250,000 jobs a month.

What to do? With the debt ceiling approaching and the gravitational pull of the 2010 elections increasing, the White House can’t go back to Congress with a formal bill to enlarge the stimulus package. Four simpler moves would be to:

(1) Use existing authority under both the stimulus package enacted earlier this year and the nefarious TARP bailout fund — extending and combining them into a fund to make up for state and local cuts in public school budgets, childrens’ health, public health (we need workers to administer swine flu vaccine) and public transportation. Instead of bailing out banks and giant automakers, we should switch to bailing out public services that average people need.

(2) Propose a one-year payroll tax holiday on the first $20,000 of income. Republicans as well as Blue Dog Dems could go along with this, and it would be a highly progressive tax cut since 80 percent of Americans pay more in payroll taxes than they do in income taxes.

(3) Give small businesses a “new jobs tax credit” for every net new job created over the next year. Granted, under normal circumstances this sort of jobs credit doesn’t have much effect, and it’s difficult to separate hires that would have happened anyway from net new ones. But we’re not in normal circumstances; small businesses, which are responsible for most new jobs, still aren’t hiring. They need a boost.

(4) Dramatically expand the Small Business Administration’s lending programs and have the Fed buy up the SBA’s debt. Big banks are not lending to small businesses. TARP has been an utter failure in this regard. The SBA and the Fed should circumvent them and help small businesses get the capital they need, so they can start hiring again.

The politics of these four steps aren’t difficult. It would be hard to get a new stimulus package through Congress, but no member who’s up for reelection next year when unemployment is likely to be in double digits wants to be accused by rivals of voting against steps to help small businesses, public schools, childrens’ health, and average working people who need a tax cut.

Tomorrow (Tuesday) is a critical day in the saga of the public option. Democrats Charles Schumer (New York) and Jay Rockefeller (West Virginia) are introducing an amendment to include the public option in the bill to be reported out by the Senate Finance Committee — the committee anointed by the White House as its favored vehicle for getting health care reform.

Before you read another word, call and email the Senate offices of Democrats Max Baucus (Montana), Tom Carper (Delaware), Robert Menendez (New Jersey), Kent Conrad (North Dakota), Jeff Bingaman (New Mexico), John Kerry (MA), Blanche Lincoln (Arkansas), Ron Wyden (Oregon), Debbie Stabenow (Michigan), Maria Cantwell (Washington), and Bill Nelson (Florida) — telling them you want them to vote in favor of the public option amendment. And get everyone you know in these states to do the same. Hell, you might as well phone and email Republican Olympia Snowe (Maine) and make the same pitch.

Background: Every dollar squeezed out of Big Pharma and Big Insurance is a dollar less that you’ll have to pay either in healthcare costs or in taxes to cover healthcare costs. The two most direct ways to squeeze future profits are allowing Medicare to use its huge bargaining leverage to negotiate lower drug prices, and creating a public insurance option to compete with private insurers and also use its bargaining clout to get lower prices and thereby push private insurers to offer lower rates.

But last January, the White House made a Faustian bargain with Big Pharma and Big Insurance, essentially scuttling both of these profit-squeezing mechanisms in return for these industries’ agreement not to oppose healthcare legislation with platoons of lobbyists and millions of dollars of TV ads, and Pharma’s willingness to cut drug prices by some $80 billion over the next ten years. The White House promised these industries they’d come out way ahead — getting tens of millions of new customers who’d be buying private health insurance policies and thereby paying for an almost endless supply of new drugs. Healthcare reform would be, in short, a bonanza.

Big Pharma and Big Insurance have so far delivered on their side of the deal. In fact, Big Pharma has shelled out $120 million in advertisements in favor of reform. Now the White House is delivering on its side.

Last Thursday, for example, the Senate Finance Committee rejected Ben Nelson’s amendment to require Big Pharma to give some $160 billion in discounts to Medicare — thereby reducing the bonanza Pharma would reap from the healthcare bill. Not surprisingly, all Republicans voted against the amendment. But it was defeated only because Dems Baucus, Carper, and Menendez voted with the Republicans.

Carper later explained to the New York Times why he voted with the Republicans. The amendment, he said, would “undermine our ability to pass” health care reform, because the White House had made a deal with Big Pharma by which the industry wouldn’t oppose healthcare reform — and White House officials had told him “a deal is a deal.” The Times described the vote as a “big victory” for the White House.

Schumer voted for the amendment. He said he was “not at the table” when the White House and Big Pharma made their deal so didn’t feel bound by it. But even if he had been at the table, he wouldn’t be bound. No member of the Senate is bound to a deal made between industry and the White House. Congress is a separate branch of government.

Big Pharma and big insurance hate the public insurance option even more than they hate big Medicare discounts. And although the President has sounded as if he would welcome it, political operatives in the White House have quietly reassured the industries that it won’t be included in the final bill. At most, the bill would allow the formation of non-profit “cooperatives” that wouldn’t have the scale or authority to squeeze the profits of private industry, or a “trigger” that would allow states to form public insurance options eventually if certain goals for cost savings and coverage weren’t met.

But the public option lives on, nonetheless. It’s still in the Senate Health, Education, Labor, and Pension bill. It still headlines the House bills, and Speaker Nancy Pelosi says she’s still committed to it. The latest Times/CBS poll shows 65 percent of the public in favor of it.

Now, Schumer and Rockefeller are introducing a public option amendment in the Senate Finance Committee. Carper, Menendez, Baucus, and other Dems on the Committee should vote for it, or be forced to pay a price if they don’t.
