You're not wrong, but I will say this:
Despite their position as the #1 wrestling company in the US, of that top 3 (WWE, AEW, ROH) WWE is the one most dependent on a consistent cash flow. Sinclair's total assets are valued at nearly $6 Billion, WWE's are valued at around $700 Million in comparison. Moreover, ROH is a subsidiary of a conglomerate with hands in many different media organizations; they're a part of a corporation that's very much insulated from many of the immediate shocks borne from this pandemic. Vince's money (or his valuation, at the very least), on the other hand, is almost completely tied up with WWE's business operations, which means his fate is very much WWE's. He won't be broke if the WWE were to hypothetically go out of business, but he would definitely be in a bad way.
AEW's in a similar position, in that Shahid Khan's money isn't totally tied up in AEW (many sports organizations, yes, but he made the bulk of his fortune from manufacturing auto parts) and he's far, far more wealthy than Vince, meaning that he's better positioned to keep paying people while shutting shows down. Hell, the very existence of AEW is a testament to his wealth: he pumped a bunch of money into what essentially amounts to a gift for his son, namely a readymade national wrestling organization that Tony can play with to his heart's content. Now Tony, unlike Dixie Carter for example, has done a very good job managing his gift business. But it's still a paramount example of his wealth and privilege nonetheless.
Does this excuse what Vince has done? fukk No. All the problems that would result from them shutting down are problems that existed long before COVID-19 existed, and he either ignored the warning signs or tried to paper over the cracks repeatedly (house show revenues and live gate revenues in general, an overly bloated roster, overreliance on rights fees deals to buttress the depressed wrestling wing of the business, killing their PPV business for the WWE network followed by being completely unable to grow the Network's user base beyond 2 million, overreliance on a small handful of aging stars and not creating/capitalizing on wrestlers that could potentially bring new audiences to the product, not replenishing their aging audience in general...I could really go on; I used to get looks at the quarterly shareholder reports for a time and these were all subjects addressed both in those documents and the meetings proper). But I at least understand the twisted circumstances that produces a scenario where Vince repeatedly shoots himself in the foot then thinks that cutting off his nose will make everything better.
