Hillary Clinton's speech will put focus on economics

In a speech intended to outline the economic vision she will present throughout her presidential campaign, Hillary Rodham Clinton on Monday will call for an aggressive rethinking of domestic policy with the single purpose of lifting middle-class incomes that have stagnated for years despite the growth of the economy.

Ms. Clinton will present a stark assessment of a middle class whose weekly earnings have virtually stalled for 15 years, and she will criticize “trickle down” Republican policies as having contributed to a vast concentration of wealth among the richest Americans, according to campaign aides. They offered a preview of the speech, to be delivered at the New School in New York, on the condition of anonymity.

The emphasis on what economists have called “the great wage slowdown” of the 21st century is the result of Ms. Clinton’s months of conversations with more than 200 domestic policy experts and dozens of economists.
