Marc Rowan, a contender for what may be the most important economics job in the U.S. government, is the CEO of Apollo Global Management, a behemoth in private equity, an industry notorious for its cutthroat profit-at-any-cost standards .

The 62-year-old executive’s rise to Donald Trump’s Cabinet, if nominated and confirmed, could mark a major victory for one of the most powerful (and often despised) financial sectors.

As Treasury Secretary, Rowan would directly oversee the Financial Stability Oversight Council, which is nominally responsible for overseeing the “non-bank” financial system, including the private equity sector in which he is currently a major player. The Treasury Department also houses the IRS and the Office of the Comptroller of the Coin, or OCC, which oversees banks.

In fact, as Treasury Secretary, Rowan could ensure that these regulatory bodies continue to treat private equity as they always have, under both Democratic and Republican administrations. That is, left largely alone.

“That regulation really doesn’t exist,” said Bill Lazonick, president of the nonprofit Academic-Industry Research Network. “You don’t even know what private equity owns; everything is protected by different types of transactions and corporate structures.”

It’s impossible to know what kind of Treasury Secretary Rowan would be if picked. It’s not uncommon for industry leaders to join the government agencies that oversee the companies they previously worked for, and their reputations are, shall we say, mixed.
