Hillary Clinton ripped Donald Trump’s economic plan Thursday, saying her GOP rival would hurt the poor and middle class and help only the super-rich.

“He wants America to work for him and his friends at the expense of everyone else. He would give trillions in tax cuts to big corporations, millionaires and Wall Street money managers,” said Clinton, speaking at an aeronautical manufacturer in Warren, Mich.

Clinton also discussed her own plan to hike taxes on the wealthiest Americans.
