Money is not a motivating factor. Money doesn't thrill me or make me play better because there are benefits to being wealthy. I'm just happy with a ball at my feet. My motivation comes from playing the game I love. If I wasn't paid to be a professional footballer I would willingly play for nothing.
There's always an imbalance with actors and actresses in the industry. And I think because there are just fewer movies overall being made it's that trickle down effect.
