True, indeed.
Generally, at least in the US, commercial producers do a great deal toward supporting nonprofit theaters by paying them to mount tryouts of their new shows. If the show is a hit, the nonprofit stands to make quite a bit more money, through deals far more favorable to them than the RSC’s. This woman seems completely oblivious to this practice in the US, and yet somehow she offers her opinion as to how government should fund more government-favored arts.
