What does revenue have to do with margins. You didn't mention costs anywhere in your statement.
My point about revenue was that games are pulling in more money than film and TV and we all know they cost less to make, and film and TV has good pay so therefore the games industry can afford similar rates, if not more.
There isn't any business on earth that compares to the margins of HFT firms. Regardless they aren't asking for big tech or HFT level salaries.
