Outlining her economic agenda in a speech Monday, Hillary Clinton took aim at her Republican rivals for what she described as "mean-spirited" policies.

Clinton advocated for the middle class and a higher minimum wage as part of her "new economic reform" on Monday morning while calling out Republican candidates like Jeb Bush for being stuck in the past.

The Democratic front-runner took her first shot at Bush's comment that Americans need to work more hours. The former Florida governor had been talking about the difficulty some Americans face in getting full-time work, but the statement has been wisely interpreted as suggesting people aren't working hard enough.

"Well, he must not have met very many American workers," Clinton said to the New York City crowd. "Let him tell that to the nurse who stands on her feet all day or the teacher who is in that classroom, or the trucker who drives all night. Let him tell that to the fast-food workers marching in the streets for better pay. They don't need a lecture. They need a raise."

Clinton also criticized two other candidates by name in her speech, Scott Walker and Marco Rubio. She condemned Walker's "mean-spirited, misguided attacks" on workers' rights, stating that he decreased the power of labor unions. Clinton also bashed Rubio's tax plan, calling it a "budget-busting giveaway."

Just minutes after her speech, Clinton's campaign released a fact sheet of Clinton's vision for the economy. In addition to laying out her three-point plan for strong, fair and long-term growth, she released a listing bashing the economic plans of eight different Republican candidates: Bush, Walker, Rubio, Chris Christie, Rand Paul, Rick Perry, Ted Cruz and John Kasich.

"Despite attempts to dress up their old ideas in new language, the GOP's proposals would disproportionately benefit the wealthy and big corporations at the expense of middle class and working families," the fact sheet says.

Clinton also rallied against the newly emerging "so-called gig economy," stating that it offers "exciting opportunities but raises hard questions about workplace protections and what a good job will look like in the future." She implicitly criticized companies such as Uber and AirBnB, vowing "to crack down on employers who misclassify workers as independent contractors," which she referred to as "wage theft."
