With advice from more than 200 policy experts, Hillary Rodham Clinton is trying to answer what has emerged as a central question of her early presidential campaign strategy: how to address the anger about income inequality without overly vilifying the wealthy.

Mrs. Clinton has not had to wade into domestic policy since before she became secretary of state in 2009, and she has spent the past few months engaged in policy discussions with economists on the left and closer to the Democratic Party’s center who are grappling with the discontent set off by the gap between rich and poor. Sorting through the often divergent advice to develop an economic plan could affect the timing and planning of the official announcement of her campaign.

Although people close to Mrs. Clinton say she has not yet settled on a specific platform, she is expected to embrace several principles. They include standard Democratic initiatives like raising the minimum wage, investing in infrastructure, closing corporate tax loopholes and cutting taxes for the middle class. Other ideas are newer, such as providing incentives to corporations to increase profit-sharing with employees and changing labor laws to give workers more collective bargaining power.

Behind many of these proposals is a philosophy, endorsed by Mrs. Clinton’s closest economic advisers and often referred to as inclusive capitalism, that contends that a majority of Americans do not want to punish the rich; they just want to feel that they, too, have a chance to succeed. It also calls for corporations to put less emphasis on short-term profits that increase shareholder value and to invest more in employees, the environment and communities.
