He put himself in a position where he was always making good money off of the shows and he obviously saved some of it. He could sure come up with some hilarious stuff in his rants when he was managing. You can't find a better historian of the business than Cornette.I don't agree with everything Corny says, but it's part of his charm, haha. His mouth is what enabled him and the people he managed to draw money back in the day when the business was still heavily reliant on ticket revenue. I largely prefer the product of his day to what the promotions are putting on TV now (the current product was lousy even before any COVID restrictions entered the picture).
One of the tricky parts about the wrestling business is how a person can extend his or her career beyond taking bumps in the ring by acting as a manager, match agent, ambassador, etc. Also, many of the ex-wrestlers either didn't make great money or didn't manage the money they made too well, so they hold something back in shoot interviews because they don't want to tick off anyone who might give them another job. Cornette is financially secure enough that he doesn't need to kiss up to anyone in the business, so he says exactly what he's thinking.
Agree with you wholeheartedly that the old time stuff is far superior.
