When people talk about pay gaps between executives and rank-and-filers, they generally mean pay gaps between individuals, not pay gaps between collectives (in this case, the 7 executives vs the 2 million employees).
There's a popular narrative that CEO compensation is at the expense of workers, that workers could be paid a livable wage if only executives could do without their extravagent bonuses. It's commonly referenced with respect to Walmart. I believe this is the myth the OP was attempting to dispel.
