Global markets are crashing down today. Asia (Hang Seng down 12.7%, Nikkei 225 fell 6.4%) and Europe (Dow Jones Euro Stoxx 50 crumbled by 5.9% and the FTSE 100 index tumbled 5.4%) are collapsing in unison. And in the last year, they have lost 51% of their value -- destroying $29.6 trillion in stock market value. You may have noticed that stockholders are the silent majority of the financial crisis. This is the group of citizens that Richard Nixon tried to mobilize to win elections. And it's the same group that John McCain's advisor, Phil Gramm, talks about when he says Americans are Whiners.

There are plenty of corporations and financial institutions that can afford lobbyists. The clients of lobbyists don't whine -- they get bailouts. As vice chairman of UBS AG (NYSE: UBS), Gramm is one of the lobbyists that the average taxpayer can't afford, so we end up paying to bail out those who can. How much? Commercial Paper (CP) gets $540 billion; Fannie Mae (NYSE: FNM), Freddie Mac (NYSE: FRE), and American International Group (NYSE: AIG) get $322.8 billion; and the top nine banks get $125 billion to pay bonuses (since Hank Paulson did not require them to lend it out).

Even if stockholders could hire lobbyists, it is unlikely that governments would be able to come up with enough cash to reimburse us for the $29.6 trillion we've lost so far -- or for the additional $20 trillion we could lose if things keep going the way they have been. With confidence lost that governments will solve the problem, people are now trying to cut their losses before they get even worse.

That lack of confidence is what will drive global stock markets for the foreseeable future.

As investors await today's start of earnings season, they should remember that Wall Street's equity analysts blew it in the fourth quarter, overestimating profit by 33.5 percentage points, the biggest miss ever, according to Bloomberg News.

"Merrill Lynch & Co.(NYSE: MER), Bank of America Corp. (NYSE: BAC) and the rest of the securities industry aren't losing credibility because of anything sinister," the story says. "The problem is they didn't get their math right after credit markets froze nine months ago."

I am not terribly optimistic that analysts have improved much in the first quarter. Earnings estimates are probably still way too high. Many, many companies are going to miss their earnings estimates. This will erode Wall Street's credibility even further.

Richard Weiss of City National Bank told Bloomberg that first quarter results will be a "big wake-up" call for some analysts. Some may lose their six- and seven-figure jobs because of it.

The lesson here is for investors to do their own homework. Anyone who doesn't have the time or motivation to do it should either hire an adviser or buy index funds.

These days, you can't take Wall Street's word for anything.
