DETROIT — Hillary Clinton plans to use a speech Thursday to attack Donald Trump for putting forward an economic plan this week that in Clinton’s estimation “only benefits millionaires like himself,” according to aides to the Democratic presidential nominee.

In a rebuttal to Trump’s speech here Monday, Clinton will argue that her economic agenda, by contrast, is focused on helping lower- and middle-class families. Aides say she plans to highlight previously released proposals that include investing in job creation, making public college tuition-free for most families and raising taxes on corporations and the wealthy.

Clinton plans to deliver her speech in nearby Macomb County, a location selected with electoral politics in mind. The largely blue-collar jurisdiction has sided with the Democratic nominee four times and the Republican nominee four times during the past eight presidential elections.

Aides say Clinton will zero in on a Trump proposal to dramatically reduce taxes on “pass-through” businesses, which do not pay corporate income taxes but whose owners are taxed at individual rates on their share of profits.

Such entities are the most common structure for small businesses — which would benefit from Trump’s plan — but they are also heavily utilized by the scores of companies that make up the Trump Organization. Clinton will argue that the real estate mogul is attempting to give himself “a backdoor tax cut” and characterize his proposal as the “Trump Loophole,” aides to the Democrat said.

Clinton aides requested anonymity to preview her speech before it is delivered.

Clinton also plans to take aim at a provision in Trump’s economic plan that repeals the estate tax, another measure she says would benefit his family personally. Earlier this week in Florida, Clinton branded that provision as Trump’s “friends-and-families discount.”

More broadly, Clinton plans to argue that Trump’s plan is weighted too heavily toward helping the wealthy and corporations and that it would “balloon the national debt,” aides said.

Clinton arrived in Michigan on Wednesday night and attended a fundraiser in Birmingham, a suburb of Detroit. Donors paid $25,000 each to attend, according to a Clinton aide. They were entertained by legendary soul singer Aretha Franklin.

Proceeds were to benefit the Hillary Victory Fund, a joint venture of the Clinton campaign, Democratic National Committee and Democratic state parties.
