That's what people don't get about the WWE.
They really don't care about making money they care about taking over. The WWE didn't need to raid ROH stars in the mid 00s, they didn't need to raid the AWAs entire roster and prevent Verne from running shows with 100 people in the audience, they didn't need to sign ECW talent only to job them with no build, they didn't need to job out a UFC champion returning to the WWE in Brock Lesnar on his first match.
All of those things did not make the WWE more money. It just made them more able to be the big fish in a small small pond.
And when you get down to it thats really all Vince and HHH can do. They can't grow their company and the art of wrestling, they can only take advantage of the marks that think they can all get along and all make money.
