Imagine a McDonalds cook complaining the store brought in 2 million a year and he making minimum wage.
I'm not going to McDonald's to have that cook make my food though
I'm not buying merchandise with that cook's face/catchphrase/logo on it
People go to McDonald's because they expect it to be the same as every other McDonald's they've ever been to, regardless of whether it's on the West Coast, Mississippi, in the suburbs, downtown, etc. The cooks don't matter, they're easily replaceable. Their job is to cook the exact same food in the exact same way.
You can't say the same for a wrestler. Say what you want about Enzo, but not many had his charisma or skills on the mic. Not many could move merchandise like he apparently did. You just can't replace him with another "cook" and have no one be able to tell the difference.
