Why can't American fighters sell the same amount of tickets as UK fighters?

[Fenster]

By the way, that 42,000 is a fudged number, they "comp" the tickets in the States, which means they give away mass unsold seats at the last minute to make it look better on TV (like the Oscars), literally take people off the streets. Whatever number they declare halve it (I was told that by a man that earns a living through selling tickets)
