Can Wall Street Billionaires Deliver on Trump’s Blue-Collar Promise?

When Donald J. Trump first ran for the White House in 2016, his closing campaign advertisement lamented the influence of Wall Street in Washington, flashing ominous images of big banks and the billionaire liberal philanthropist George Soros.

Now, as president-elect, Mr. Trump has tapped two denizens of Wall Street to run his economic agenda. Scott Bessent, who invested money for Mr. Soros for more than a decade, is his pick for Treasury secretary, and Howard Lutnick, the chief executive of Cantor Fitzgerald, will be nominated to lead the Commerce Department. Mr. Trump’s choices to lead his economic team show the prominence of billionaire investors in setting an agenda that is supposed to fuel a “blue-collar boom” but that skeptics think will mostly benefit the rich.

As Mr. Trump prepares to assume the presidency in January, business owners and investors are closely attuned to which of his economic promises he will ultimately follow through on. He has promised to slash tax rates, impose hefty tariffs on China and other countries, and deport millions of immigrants who work in American farms and businesses.

The selections of Mr. Bessent and Mr. Lutnick cement a hold by Wall Street executives over the two most important economic posts in any administration. The picks are drawing blowback from Democrats and left-leaning groups, who assailed Mr. Trump for giving top jobs to rich donors and suggested that they would soon be working to create new tax breaks for the rich, not those who are struggling.

“For all his talk of looking out for working-class Americans, President-elect Trump’s choice of a billionaire hedge fund manager to lead the Treasury Department shows he just wants to keep a rigged system that only works for big corporations and the very wealthy,” said Tony Carrk, the executive director of the government watchdog group Accountable.US.

Yet the decision to tap Mr. Bessent and Mr. Lutnick is raising speculation that Mr. Trump could take a more market-friendly approach to many of his economic policies than some had feared because of his professed love of tariffs, which had the potential for igniting a global trade war.
