Well, that's just sad to treat a fan base like that imo.
The $50 fan is the fan that comes to multiple games during the course of a season, pays the ridiculous parking fees, spends too much at the concession stands for sub-standard food, buys the extremly overpriced merch, and supports the franchise. Without the lowly $50 fan as you call them, the team folds.
Make the entire stadium $250+ fans and see what happens.
