Democratic presidential nominee Hillary Clinton gave details Thursday of how her economic plan would grow the number of jobs and increase incomes, contrasting her proposals against opponent Donald Trump's platform.
She spoke in Warren, Michigan, a suburb of Detroit, at a former automotive supplier that is now an aerospace manufacturer.
Clinton said her economic programme amounts to "the largest investment in good-paying jobs since World War II" and would put Americans to work building and modernizing US roads, bridges, ports and airports.
"We are way over due for this," she said, slamming Trump for offering an economic plan that she said would cost millions of US jobs.
She cited an independent analysis saying her plan would create more than 10 million new jobs, while Trump's would result in a loss of 3.4 million jobs.
Clinton repeated her unequivocal opposition to the Trans-Pacific Partnership (TPP) trade deal.
"I oppose it now, I'll oppose it after the election, and I'll oppose it as president," she said, alleging that earlier trade deals have been sold to the American people "with rosy scenarios that didn't pan out."
The answer is to "finally make trade work for us, not against us," Clinton said.
She said while serving in the US Senate she fought to stop unfair practices like currency manipulation and theft of intellectual property, and as president would "stand up to China and anyone else who tries to take advantage of American workers and companies."
Clinton said she would increase enforcement efforts by appointing a new chief trade prosecutor, tripling the number of enforcement officers and imposing targeted tariffs when countries break the rules.
The broad speech covered several other proposals - from cost-free college for middle class Americans to broadband internet access for every US household by 2020 - showing that Clinton's positions have shifted to the left in the process of winning the Democratic nomination over self-described democratic socialist Bernie Sanders.
She called for Wall Street, corporations and the wealthy to "pay their fair share" and for a guaranteed share for workers' in corporate profits they help generate.
In a critique of Trump's economic plan, she said it would roll back tough rules on the financial industry and give trillions of dollars in tax cuts to big corporations, millionaires and Wall Street money managers.
A new tax loophole Trump proposed Monday when he offered his economic vision in a speech in Detroit would benefit him personally, she said. It would allow him to pay less than half the current tax rate on income from many of his companies. In addition the 400 richest taxpayers in America would get an average tax cut of more than 15 million dollars a year from the loophole.
