FOR THE RECORD
Tour houses and presenters set ticket prices and are the ones who like to market "Direct from Broadway". Go for Them, NOT the show's lead producers.
A show being Equity or Non-Equity has no bearing on the initial investment in the physical production. Also, depending on the producer, it is not at all unusual for the cast to be non-union, while the musicians and stage crew are fully union, but that is a whole other conversation.
As far as actor pay goes, yes, non-union actors are not protected by the union's collective bargaining, HOWEVER, there are absolutely cases where an actor on a non-Equity tour contract is making equal pay or even more pay than an actor on a Union tour. There are many many factors at play other than pay in that choice as well.
An actor's ability has ZERO reflection upon their union status. (Though yes, certain producers tend to hire bargain basement...)
