As a rule, any creation of a new behemoth generates buzz. But this time, there has been equally breathless talk about why—Why, that is, CVS would offer what, presumably, would be a jaw-dropping $13 billion premium for Aetna’s stock? (The reported $200-a-share offer would have been roughly $40 bucks above Aetna’s closing share price on Wednesday, before word of the potential deal leaked out on Thursday, sending Aetna’s stock due north. On June 30, according to the insurer’s latest 10-Q, the company had 332 million shares outstanding.)

For the answer, all eyes turned to that other buzz-worthy behemoth, Amazon.com, which has given signs it’s moving into CVS Health’s pharmacy territory. Those rumors got more weight after the St. Louis Post-Dispatch reported that “The Everything Store” had applied for and received wholesale pharmacy licenses in at least 12 states.

Others pointed to more fundamental concerns of competition, suggesting that CVS Health needed Aetna (or something like it) to better compete with UnitedHealth Group, which has both a managed care organization (MCO) and a pharmacy benefit manager (PBM) under the same roof. Indeed, the Oracle of Delphi award ought to go to Robert Flynn, a principal at Fuld & Company, who spelled out back in June “Six Reasons Why CVS Health Should Acquire Aetna . . . Soon.” (Reading the post now, in hindsight, it’s actually pretty brilliant.)

But the purported offer got me thinking not about the why but about the who—particularly, about the leader of the sought-after company, Aetna CEO Mark Bertolini.

Bertolini has figured out a clever way of rewarding shareholders. And that’s largely by focusing on the wellbeing of his employees. Witness one high-profile move the CEO made two and a half years ago, when Bertolini announced at the annual JPMorgan health confab that Aetna would substantially raise the minimum wage of its U.S. employees and also help offset worker healthcare costs.

Though, at the time, others scoffed at the largesse, Aetna’s shareholders have benefitted remarkably. Since that announcement in January of 2015, Aetna has returned an annualized 29% to its stockholders including dividends, compared with 11.1% for the S&P 500. Shareholders who held stock on the date of Bertolini’s announcement and still hold it today have seen the value of their original stake more than double (compared with the more modest 34% gain for the S&P 500 during the same period).

That said, when I spoke to Bertolini late in the summer, he didn’t seem remotely satisfied—at least with the direction that much of America’s corporate enterprise seems to be headed. Indeed, he says, if the capitalist system that has driven the American Experiment to success is to continue driving to success, it needs to figure out a way for American workers to share more, and feel a greater stake in, that prosperity.

“Here’s the way I think about it,” he told me at the end of August. “CEOs are required to paint a stark reality of what the world looks like in five to 10 years. So it’s not what it is today versus other alternatives today. It’s about what should we be versus what it’s going to look like in five to 10 years from now. And doing nothing, in the current model around capitalism, will destroy capitalism. When 65% of people under the age of 35 believe that socialism is a better model, we have a problem. We have a problem. So unless we change it, it will change—and maybe not in a good way.”

Bertolini continued: “My call to other CEOs is: ‘If we don’t step up to change it, as captains of capitalism, somebody else will—and it will not be pretty when that happens.’”

“I think there’s a clarion call to make a difference here,” he went on. “And unless we do it on our own—unless people speak out and talk about how we can be better, and we can lift all boats versus just the 1 percent—We’re in for a really bad time. So I’m very focused on that message with a lot of folks because that’s the reality in the future.”

When I saw Bertolini in late September, at Fortune’s and Time’s CEO Initiative, he reiterated the sentiment.

It seems unlikely that Aetna’s chief would remain in the new corporate fold if the purported CVS acquisition were to happen. And one has to wonder whether the corporate culture Bertolini has built there would survive as well. It would be too bad if it didn’t—and seemingly, for shareholders, too.
