Hillary Clinton said on Thursday that she wanted “to make our economy work for everyone, not just those at the top.” It’s a philosophy she put forward over a year ago at the start of her campaign. Since then, her proposals to achieve this goal — mainly through tax fairness, job creation and higher wages — have become much more detailed and offer an even sharper contrast to Donald Trump’s economic ideas, which she ripped apart in her speech.

Mrs. Clinton says her first priority is to create jobs, primarily through public investments in infrastructure, like roads, bridges, school renovations, affordable housing, water systems, electrical grids, broadband internet and renewable energy.

To help pay for the plan, initially $275 billion over five years, she has proposed several tax increases on high earners, including the “Buffett rule” for a minimum tax of 30 percent on those who make more than $1 million, a 4 percent surcharge on incomes over $5 million and a limit on deductions. Mr. Trump has also said he would rebuild the nation’s infrastructure. But the multitrillion-dollar income tax cuts for corporations and the wealthy in his plan would preclude such investments. And his plan to repeal the estate tax, Mrs. Clinton rightly pointed out, would not help a vast majority of Americans and deplete the Treasury of hundreds of billion of dollars of revenue.

Creating greater “fairness” in the economy is another priority for Mrs. Clinton — one to be achieved largely through tax policy changes. To help curb the decades-long trend of rising corporate profits and falling wages, she called for a new business tax credit to reward companies that have profit-sharing plans. Mr. Trump has said little about inequality and has no such proposal.
