If some billionaire wanted his own wrestling federation, and had seemingly unlimited amounts of money, how far could he get it? It's a market that only has one real competition with a lot of flaws, and it's a market that can make you a lot of money; WWE is proof of that. With that much money you would have no issues with stealing WWE talent as you can pay them equal amounts (or more) and promise better booking. You won't have any issues having a decent venue, and could easily afford marketing costs. You would have all the wealth WWE has and more. Of course this is hypothetical, but it's fun to think about.
