How does Ben Schwartz and friends get an audience of 3,500+ people to pay $60+ to see a show, but my local Chicago improv theaters can’t get 30 people to spend $10 to see a show?

Clearly people enjoy the art form, why can’t we turn it into regular audiences at our theaters?

Ben Schwartz is touring, but no site lists who the co performers are. Can anyone who has seen the show say the location and who was there?

I was at the Milwaukee, WI show last night, but missed the intro of everyone's names! Such a fun night though, and I'd like to know more about the other actors.
