You're overlooking the nature of the beast.
Those 150 million Americans have no loyalty. They don't give a damn about Disney or other "legacy" institutions. They were never the ones attending Disney parks or films -- or rather, they were in the minority.
My guess: Iger might try to make Disney even more woke in the hopes of attracting hipster types. But they've probably moved on to the latest fad elsewhere.
In addition, liberals have lower birthrates. No children, or few children, or sterilization. They can never sustain any society.
True. That's why Disney hosts "Gay Days" in June every year. But that's only one month.
