Kos is right -- if this Wall Street Journal editorial is any indication, James Webb is no conservative:

The most important--and unfortunately the least debated--issue in politics today is our society's steady drift toward a class-based system, the likes of which we have not seen since the 19th century. America's top tier has grown infinitely richer and more removed over the past 25 years. It is not unfair to say that they are literally living in a different country. Few among them send their children to public schools; fewer still send their loved ones to fight our wars. They own most of our stocks, making the stock market an unreliable indicator of the economic health of working people. The top 1% now takes in an astounding 16% of national income, up from 8% in 1980. The tax codes protect them, just as they protect corporate America, through a vast system of loopholes....

In the age of globalization and outsourcing, and with a vast underground labor pool from illegal immigration, the average American worker is seeing a different life and a troubling future. Trickle-down economics didn't happen. Despite the vaunted all-time highs of the stock market, wages and salaries are at all-time lows as a percentage of the national wealth. At the same time, medical costs have risen 73% in the last six years alone. Half of that increase comes from wage-earners' pockets rather than from insurance, and 47 million Americans have no medical insurance at all.

Manufacturing jobs are disappearing. Many earned pension programs have collapsed in the wake of corporate "reorganization." And workers' ability to negotiate their futures has been eviscerated by the twin threats of modern corporate America: If they complain too loudly, their jobs might either be outsourced overseas or given to illegal immigrants....

America's elites need to understand this reality in terms of their own self-interest. A recent survey in the Economist warned that globalization was affecting the U.S. differently than other "First World" nations, and that white-collar jobs were in as much danger as the blue-collar positions which have thus far been ravaged by outsourcing and illegal immigration. That survey then warned that "unless a solution is found to sluggish real wages and rising inequality, there is a serious risk of a protectionist backlash" in America that would take us away from what they view to be the "biggest economic stimulus in world history."

More troubling is this: If it remains unchecked, this bifurcation of opportunities and advantages along class lines has the potential to bring a period of political unrest. Up to now, most American workers have simply been worried about their job prospects. Once they understand that there are (and were) clear alternatives to the policies that have dislocated careers and altered futures, they will demand more accountability from the leaders who have failed to protect their interests. The "Wal-Marting" of cheap consumer products brought in from places like China, and the easy money from low-interest home mortgage refinancing, have softened the blows in recent years. But the balance point is tipping in both cases, away from the consumer and away from our national interest.

With this new Congress, and heading into an important presidential election in 2008, American workers have a chance to be heard in ways that have eluded them for more than a decade. Nothing is more important for the health of our society than to grant them the validity of their concerns. And our government leaders have no greater duty than to confront the growing unfairness in this age of globalization.

This country is splitting into three pieces. As a result of the internationalization of the economy, the people at the top have never had it so good. The middle class is continuing to get squeezed by stagnant wages and rising cost of living. And we are in danger of creating a permanent underclass. We must reexamine our tax and trade policies and reinstitute notions of fairness, and also enforce our existing trade laws so that free trade becomes fair trade.

a) Have little effect on the income of the richest Americans -- though their capital gains will fall dramatically;

b) Benefit some middle-class Americans in the form of preserving their import-competing jobs, while hurting other middle-class Americans by destroying their import-reliant jobs;

c) Have a mixed effect on the poorest Americans -- even if their wages rise from halting illegal immigration, their costs of living will rise even higher from the higher price of goods in the stores.

UPDATE: Arnold Kling and Greg Mankiw have more. Mankiw makes a good point here:

[L]et's suppose for a moment that a free-market economist were hired by the Dems to offer policy advice. If the boss's goal is to reduce income inequality, what is the best way to do that?

The standard Democratic fare would be quickly rejected. Erecting barriers to trade, raising the minimum wage, encouraging the cartelization of labor via unions, and bashing Wal-Mart are inefficient and poorly targeted ways to redistribute income.

The tax system is probably the best vehicle to accomplish the Dems' goal. One possibility would be to reduce the payroll tax rate and to make up the lost revenue by increasing, or perhaps even eliminating, the cap on taxable payroll. That would benefit, approximately, the bottom 90 percent of the income distribution.

This policy change would, of course, have an efficiency cost. By raising taxes on taxpayers who already face the highest tax rates, the deadweight losses of the tax system would surely rise. But almost any attempt to achieve a more equal distribution of income would entail efficiency costs. The Dems' goal should be to minimize the efficiency cost for any given amount of redistribution. And that is most likely accomplished through the tax system rather than by more heavy-handed market interventions.
