It’s uncertain...none of us know the answer
What I usually lean on is that the people at WWE clearly know more about the ins and outs of running a multi billion dollar wrestling company than I ever will or care to know because they are doing it. Anyone who claims to know how to run a company better than WWE is either: full of shyt or some kind of financial genius, otherwise they’d be running one.
Just based on numbers though, a lot about WWE seems to be self sustaining, meaning, the cogs pay for the wheel. It seems like they cut their losses and whatever they are doing (good bad or terrible programming wise) seems to attract enough attendance, merchandise, viewership, and advertising dollars to keep their investors happy and turn a profit.
If I had to guess, I’d say that the talent bubble will burst soon, but not financially. WWE will always be able to attract someone like EC3 who “loves wrestling” but is cool with doing very little wrestling and making 6 figures. GREAT talent will continue to use social media to leverage their own fame and fanbases to get huge deals and huge incentives with either WWE or AEW or they will stay independent and stay in charge of their own brand.
Social media is the great equalizer and younger people understand the pull. You can run your own talent agency with you as the star by: promoting, selling your own merch, booking your own meet and greets, interacting with fans, etc. so the allure of a big wrestling company “making you a star” will die soon.
