Centering her presidential campaign on boosting incomes for middle-class Americans, Hillary Clinton on Monday will begin unveiling an economic policy agenda designed to lift working families that have experienced years of wage stagnation and economic anxiety.

In a major address in New York, the Democratic front-runner will lay out a diagnosis for why wages have been stuck and a framework to ensure that economic growth benefits more ordinary workers, according to campaign officials.

“She believes that making sure the real incomes of everyday Americans are rising steadily and strongly is the defining economic challenge of our time,” said one campaign official, who previewed Clinton’s remarks only on the condition of anonymity.

Clinton will endorse a host of popular Democratic policies such as raising the minimum wage and investing more in infrastructure. She will emphasize proposals tailored toward working women, one of her most important bases of support, such as expanding access to child care and providing workers with paid family and sick leave.

The ideas, in many ways, sound similar to the second-term agenda of President Obama, who faced an economic crisis in his first term and in his second started to more directly to address the nation’s long-running economic problems. But he has struggled to pass major legislation with a Republican-dominated Congress.

Clinton will say she wants to build on his agenda, and, in working to craft an economic vision of her own, she goes further in her emphasis on giving women more flexibility to enter the workforce and on new government efforts to change the investment and pay decisions of corporations.

Clinton’s speech, to be delivered at 10 a.m. Monday at the New School, a progressive university in Greenwich Village, will cement a leftward shift in the Democratic Party. In the aftermath of the Great Recession, concerns about the widening gap between rich and poor have risen to the top of the party’s agenda.

Clinton is carving out space between the Republican candidates, who pay more attention to growing the economy than to raising wages, and her leading Democratic primary opponent, Sen. Bernie Sanders, I-Vt., who focuses more on redistributing income to solve the inequality problem than on growth.

Clinton’s aides said she plans to assert that the Republican candidates use rhetoric designed to appeal to middle-class voters but are proposing dated, trickle-down policies from the Reagan presidency – such as tax cuts for the wealthy, with the hope that they fuel growth that eventually benefits working families.

The U.S. economy grew only 2.4 percent last year, and over the past 15 years, economic growth has slipped well below the averages of the 1980s and 1990s. Former Florida governor Jeb Bush is promising to grow the economy by 4 percent a year.

But Clinton will argue that “the measure of our economic success should be how much incomes rise for middle-class households, not an arbitrary growth figure,” according to the Clinton campaign official.

In her speech, aides said Clinton will argue that tectonic forces in the global economy are conspiring against middle-class families – such as automation and technology, which are eliminating middle-skill jobs that once provided solid incomes, as well as the new “sharing economy,” epitomized by Uber, which has created efficiency but also jobs lacking benefits and protections. But she will say that the government should enact policies to shape how these forces affect Americans.
