When presented with vivid descriptions of income inequality in America, people are deflated, rather than empowered to bring change. In surveys, they tell me that they think the politicians and the chief executives are “piggybacking off each other.” They think that the game is rigged and that the wealthy and big industries get policies that reinforce their advantage. And they do not think their voices matter.

That government and the elite appear blithely to promote globalization and economic integration, while the working population loses income, makes the frustration more intense.

Our research shows that the growth of self-identified conservatives began in the fall of 2008 with the Wall Street bailout, well before Mr. Obama embarked on his recovery and spending program. The public watched the elite and leaders of both parties rush to the rescue. The government saved irresponsible executives who bankrupted their own companies, hurt many people and threatened the welfare of the country. When Mr. Obama championed the bailout of the auto companies and allowed senior executives at bailed-out companies to take bonuses, voters concluded that he was part of the operating elite consensus. If you owned a small business that was in trouble or a home or pension that lost much of its value, you were on your own. As people across the country told me, the average citizen doesn’t “get money for free.” Their conclusion: Government works for the irresponsible, not the responsible.

Everything they witness affirms the public’s developing view of how government really works. They see a nexus of money and power, greased by special interest lobbyists and large campaign donations, that makes these outcomes irresistible. They do not believe the fundamentals have really changed in Mr. Obama’s Washington.

What should Democrats do?

The Democrats have to start detoxifying politics by proposing to severely limit or bar individual and corporate campaign contributions, which would mean a fight with the Supreme Court. They must make the case for public financing of campaigns and force the broadcast and cable networks to provide free time for candidate ads. And they must become the strongest advocates for transparency in campaign donations and in the lobbying of elected officials.

IF they want to win the trust of the public, Democrats should propose taxing lobbyist expenses and excessive chief executive bonuses and put a small fee on the sale of stocks, bonds and other financial instruments. By radically simplifying the tax code to allow only a few deductions, the Democrats would generate new revenue and remove the loopholes that allow special interests to win favorable treatment. The ordinary citizen, according to our surveys and focus groups, feels there is no way to play that game and views simplifying the tax code as an important reform.
